Squid game guards

so i haven't watched all of the squid games yet, but i have an idea of what each guard is! Circle Guard/circle: worker. cleans the bodies and cooks. Isn't allowed to speak. Triangle Guard/triangle: soldier. kills the eliminated players. isn't allowed to speak?? Square Guard/Square: Observer. makes sure the players and guards follow rules. can speak. frontman: overseer. watches the games. can speak. That's all i know! there are VIPs, but idk.. they aren't quite the same as Guards and the frontman.
