- Kacey Simon (Cymphonique Miller) is former queen of The Perfs, now lead singer of Gravity 5, Kacey Simon is confident, bold, beautiful and now on a constant campaign to take her new friends and band mates to the top of the school social ladder. She can sing, she can dance, and she's proving to Gravity 5 that she also knows how to be a true friend.
- Molly Garfunkel (Samantha Boscarino) is the new Queen of the Perfs. Molly is every bit as confident, popular and beautiful as Kacey, but she's also an evil mastermind plotting to bury Kacey once and for all.
- Zander Robbins (Max Schneider) is the new kid in school and guitarist for Gravity 5. Zander is cool, handsome and perhaps sometimes a little vain, but he is also confident, optimistic, loyal to his friends and is the one that holds the band together. A running gag in the show is that he can't stop staring at himself in the mirror. He is the one who offered Kacy a place in Gravity 5 after seeing her being put down by Molly and Grace, so if it weren't for him, Kacy would have been completely friendless.
- Stevie Baskara (Lulu Antariksa) is Gravity 5's smart, beautiful, strong-headed, tough, no-nonsense bass player. The guys love her because she is cool, but fear her because she can and will crush them, so no matter what, if you come face to face with her, you have to respect her. She's not afraid to be herself, even if it means being a total tomboy. In "How to Rock a Messy Bet" it is revealed that she has four brothers. The Perfs always refer to her as "Loserberry," much to her discomfort. Stevie is always more than willing to stick up for her friends even if it does mean being a little aggressive in behavior. She is said to have problems with "slamming" people.
- Grace King (Halston Sage) is queen bee Molly's gorgeous but naïve sidekick, in the mean girl group The Perfs. Although she tries to follow Molly's evil lead, Grace just doesn't have it in her to be mean.
- Nelson Baxter (Noah Crawford) is the tech-savvy, sci-fi loving keyboard player and DJ for Gravity 5. Nelson is confident when talking about the ladies, but completely tongue-tied when he is face to face with them, which makes him socially awkward.
- Kevin Reed (Christopher O'Neal) is the drummer for Gravity 5. Besides being constantly hungry and constantly sweating, he is awkward with the ladies but athletic enough to make every sports team just not good enough to actually play. When trying to talk to girls, he always passes out.
