A basic overview of the SHC system by @wisteria-lodge is here.

Ralph - Badger Lion

The first thing that we see Ralph do in the movie is going to a Bad-Anon meeting. His driving motivation for getting the medal is not because of the medal itself, but for everything that the medal will get him - acceptance from all of the other characters in his game. I did consider Snake primary for Ralph, since his friendship with Venellope and the characters in his game seems to be enough for him, but he's so focused on groups that I settled on Badger.

As for Ralph's secondary, he gets stuff done. He needs a medal? He deliberates about the specifics with Tapper for a bit, and then he climbs a building and goes Turbo to get it, risking his own death. He does have a Snake secondary model that he uses for other things, like taking Markowski's clothes to sneak into Hero's Duty and lying to Venellope about the tree-trimming service when they first meet. He also lies to Felix about how he didn't know that there was a party, and it's worth mentioning that Venellope calls him a liar, but it's not his primary way of doing stuff.

Venellope - Double Lion

Venellope was by far the easiest character to sort for me. I mean, "I know I'm a racer. I can feel it in my code." might be the most Lion primary sentences ever written. Even though everyone else tells her that she's just a glitch, she knows she's a racer. I mean, the first thing that she does when she first meets Ralph is race him for the medal. 

And Venellope's secondary? She's a loud Lion secondary. She knows what she wants, and she's not going to back down from it no matter what. She wants to win the race, even if it's on her own. 

Felix - Double Badger

Like Ralph, Felix is fixated on groups. He wants to include Ralph at the party, even if it's uncomfortable for both him and the other characters in his game, and he tries very hard to keep the peace. 

As for his Secondary, Felix primarily seeks out other people. He finds Calhoun when Ralph's gone Turbo, and coerces her to help him. When he gets to Sugar Rush, the first thing that he does is seek out Sour Bill. I considered an 'I-know-a-guy' Bird, but Felix doesn't collect anything else like how most Bird secondaries do. When he's locked in a dungeon, the first thing that he does is call for help. I think that a Bird Secondary would at least try to look around first. 

Calhoun - Badger Lion

She was hard to sort for me, because she's very stereotypical? I mean, she likes groups and bossing people around, so I could say that she's an Authoritarian Badger? Maybe a Snake, since she cares about Felix and her troops? She definitely doesn't like selfish people, judging by her saying that the selfish man is like a mangy dog. I'm going to cautiously say Badger, because when a Cy-bug escapes her game, she goes after it so that the other games don't have to deal with it. Snakes can do that too, obviously, but it wasn't even a question for her.
