What does it mean if a guys friend group makes fun of you?

There’s a popular friend group in my grade. I’m not in the group but know most of the people. There’s a guy ik for sure likes me, Aaron, but this girl in the group keeps yelling my name randomly as a “joke” and there’s other guys in the group that act weird. Like the other day this kid Carmen came into my class with his other friend and walks right up to me and says some random stuff and pretends he left something under MY desk so coincidentally, and then says bye to me and leaves. Carmen keeps following me around in the hallways and Aaron is always really nice and jokes around with me. I’m confused bc I used to be friends with the girl in the group and now I feel like she’s trying to make fun of me. For the past few months that whole friend group has been acting super weird and I definitely know something is going on. I just don’t know if I’m getting bullied LOL or the guys like me. I know that sounds so pick me but genuinely I’m confused. Guys usually talk to me and think I’m pretty so maybe they’re just teasing me bc they’re immature but I don't know. PLS HELP I can give more context if needed!

how do i know for sure tho that one of the guys likes me. Carmen's in one of my classes and Aaron's in two of my classes. I know Aaron likes me bc he's so fucking obvious its getting annoying but not sure about Carmen, and I'm pretty sure the girl likes Carmen. So what am I supposed to do I don't like either of them and just want both the guys to leave me alone!
