(for the boys only) how do guy friends treat each other?

So I’m a trans man, and I’ve almost always hung out around girls or non-binary people, and they always say things like “I love you platonically,” “bestie,” or like apologize for every little thing. They kinda just hug each other whenever the others are feeling down, and other stuff like that if your in a girl friend group. Anyways, I just recently got involved with a group of gaming dudes, and most of them see me as a boy, but I want to know how they kinda like interact with each other. Like, what should I do if one of them is being upset about something (one was telling me about how he was being bullied every day), I honestly don’t know how to do this lol. What should I call them, like bro and dude?
