Lincoln has a passion for comic books, especially his favorite superhero Ace Savvy who has a playing card theme as well as secret agent David Steele. Alongside his little sister Lisa, Lincoln is the family nerd. He is also, however, the primary leader of his ten sisters, as he typically plans schemes, strategies, and "operations" for better convenience, as well as to help others, that the girls more often than not follow. Lincoln has other talents, including cooking, playing video games, performing magic tricks, and coaching his younger sister Lola to prepare her for her pageants. Lincoln wears an orange polo shirt, blue jeans, gray socks, and white sneakers. Lincoln often breaks the fourth wall by talking to the audience about living with all of his sisters, and considers himself the "Man with a Plan." He tries to give helpful advice concerning sibling relationships. For the first four seasons, Lincoln attends Royal Woods Elementary School with his younger sisters Lucy, Lana, Lola, and Lisa and is a 5th grader there. In "The Loudest Thanksgiving", it is revealed that Lincoln is vulnerable to tryptophan, which causes him to fall asleep before Thanksgiving dessert is served.

She is named after one of Savino's five sisters. Lori was the roommate of her younger sister Leni even after she started attending and visiting Fairway University as of "Schooled!". In earlier episodes, Lori was often bossy, short-tempered, and condescending towards her younger siblings; however, she cares deeply about her family. Lori has a long-distance boyfriend named Bobby Santiago, the big brother of Lincoln's best friend Ronnie Anne Santiago; however, Lori enjoys seeing the two together, thinking that the two are a couple, much to their dismay. Lori wears a light blue tank top, brown cargo shorts, blue slip-on shoes, and white pearl earrings, she is tall, has big blonde hair (which is normal in the live-action projects), and stands out for being attractive. As she is the only Loud child with a driver's license, Lori usually forces her siblings to do errands for her in exchange for being transported somewhere. Lori also occasionally has intense flatulence, which she denies, claiming that the sound was made by her shoes or another object like loose floorboards or a car seat.

For the first four seasons, she is a senior at Royal Woods High School and attends school with her younger sisters Leni, Luna and Luan.

Along with Luna, Leni has the best older sister relationship with Lincoln. Leni occasionally fights with Lori over things such as clothes. Leni was hired to fold clothes at Reininger's Department Store in the Royal Woods Mall. She frequently tends to be absent-minded, which requires her siblings to correct her on things she misunderstands. She didn't have a driver's license or know how to drive Vanzilla in "Driving Miss Hazy", but Lana's Listen Out Loud podcast reveals that she is now able to drive, although she hasn't in any actual episodes due to a lack of confidence during the actual exam.

Luna is a wild and upbeat musician who owns and plays various instruments; her signature instrument is a purple Dean ML electric guitar. Her passion for music has some negative effects, as in the episode "For Bros About to Rock" it is revealed that she unintentionally "ruined" her siblings' first concerts. Along with Leni, Luna has the best older sister relationship with Lincoln. The episodes "Study Muffin" and "L is for Love" revealed that Luna is bisexual, because she is attracted both to Lincoln's male tutor Hugh and a female classmate named Sam Sharp.

EW writer Nick Romano interview with Michael Rubiner, the showrunner of the series who he plans to continue the arc of Luna but he doesn't have any end point in mind for the two of them but "with 10 girls in the family", he felt natural "to explore one of them being LGBTQ." Kevin Sullivan, the writer of the series told Insider that he wasn't barred from using the word "lesbian" in dialogue when writing the storyline for Luna and her crush Sam and said that "we just can't say those words because of how young our audience can skew but the joy of the episode, that I was proud of was that it wasn't an coming out episode. The entire family accepted her, there was no having to come out."

When her siblings confess to each other things they did, Lola often rats on them, especially Lincoln.

She wears glasses, an olive green turtleneck sweater, dark pink pants, and brown loafers. Her brown hair was revealed to be a wig in "Potty Mouth", having burnt it due to a botched nuclear experiment. Lisa often uses formal and detailed terms to refer to basic things before saying them in layman's terms. She often tends to be quite reckless and unethical with her experiments but is ultimately a good-hearted girl. A running gag is that Lisa's beakers filled with compound mixtures tend to explode, which occasionally mutate her body; as such, she has to wear dentures and a wig and has an extra toe. She is also a fan of west coast rap music and is very good at breakdancing. Despite her intellect, Lisa struggles greatly with simple things such as arts and crafts because of her stubby fingers and also struggles to form friendships with her peers. Some of Lisa's inventions include an assortment of robots, projects that she collaborated with Lincoln on, Gloweos (cookies infused with the bioluminescent DNA of the Aequorea victoria that make the consumer glow in the dark for a short time), a Urine Detector liquid that removes urine from bodies of water, Gravity Shoes that enable her to walk on the ceiling, a chocolate fountain that started out as a nuclear fusion device until she dropped her chocolate bar in it, a compatibility machine used to match up two people, robotic kangaroo legs to go with Lisa and Lily's shared kangaroo costume, overly-effective lie-detecting products, a chemical analysis machine, and a reanimator.

In the first four seasons, Lily is usually seen wearing only a diaper. From the fifth season on, Lily is seen wearing a white shirt, lavender shorts, and white booties. Lily is babysat by Lincoln on several occasions, with whom she has the best younger sister relationship along with Lucy and Lana. She has a habit of losing her diaper, which her older siblings put back on. Her siblings and her parents always change Lily's diaper in her and Lisa's room. Prior to season five, the only phrase aside from gibberish Lily says is "poo-poo", usually as her diaper flies across the screen or she needs a diaper change. Lily shares a room with her older sister Lisa and her gibberish can sometimes be translated by her older siblings. Around the end of "Washed Up", Lily is the only one who sees Lake Eddy's residential cryptid Plessy which Lincoln and Lucy wanted to find.

While originally designed to look like a hippie in a flashback seen in "Vantastic Voyage", he was later redesigned in his official debut in "Camped!" where he resembled Lynn Sr. with a longer beard. Leonard was originally a traveling fisherman as seen in "Camped!" until he got word from his son when Camp Mastodon was closing. When the treasure was found and he used his boat to save his family, Leonard offered to use the treasure to keep Camp Mastodon open as its new proprietor so that he can be closer to his family. In "Present Danger", it is revealed that Leonard is a fan of David Steele. In "Bummer Camp", Leonard learns how to be a camper from his grandchildren. The episode "Be Careful What You Fish For" revealed that Gramps lost the big toe on his right foot 30 years ago during an attack by the great white sturgeon Moby Rick who also wrecked the ship that he was on.

He is first mentioned in "Home of the Fave" and made his first physical appearance in "'Twas the Fight Before Christmas". Compared to his brother Lynn, Lance has a rather muscly build. He has a wife named Sharon and raises three children: eldest son Shane, middle daughter Shelby, and youngest son Shiloh. In "Home of the Fave", Lance was mentioned to be the favorite son of Leonard and during a family Christmas gathering, an accident would drive them apart. During "'Twas the Fight Before Christmas", Lincoln along with his sisters would devise a plan to reunite his father with his brother at Camp Mastodon. Eventually, Lynn Sr. and Lance reconciled after working together to save Lincoln, Lori, and Shelby who were stranded on a swiftly-cracking sheet of ice at Lake Mastodon. In "One False Move", Uncle Lance moves his family to Royal Woods to be closer to the Endur-Lance Gym as they move in to the house on the same street as their relatives. In "Grouse of Horrors", Lance is shown to have a fear of ghosts and can make "Lance-sagna" (his take on his brother's Lynn-sagna with more protein powder").
