Chachan would be Super High-School Level Smith! Shocking, I know. Given his timid and friendly nature, he would likely not participate at all in the murders. Though (and perhaps sadly), I could just as easily see him ending up one of the victims due to his trusting nature being a horrible fit in such a scenario.
Judge would be... Ultimate Judge/Lawman. Again, completely out of the blue here! I could see him killing if it was needed, since it is technically the rules of the game. However, he might be better suited as a sort of support role for the main character - explaining how to properly find clues and identify the killer of other murders. And then, either somehow seek to use the rules to turn the tables... or have some weird shift where he causes the most complex murder in order to ensure that the main character knows what is right and proper.
Gogon would be Super High-School Level Mathematician or War Buff. And he would totally kill to get out of this obnoxious, frustrating situation. Would likely be one of the later ones, moving things into position to push suspicion away from him when he finally does it. However, one simple slip-up will likely give his act away and bring it all crashing to the ground - resulting in him being properly identified and put to death.
