Am I just one of the guys?

I always tease around with my guy friends and we fake wrestle and they always hug me and take me down. They always give me their jackets and they always steal my scarfs and phone and fake glasses I wear. I always play catch with the football with then while the other girls jut watch and they always sing. Songs to me (when we hang out they bring their guitars because they are all musicains) and I always get them to teach me the guitar they ALWAYS tease me about random things and alot about other guys I feel really comfortable around them and they with me but I don't know do you think they see me as one of the guys or do you think they well one of them might like me? And out of the guys I hang with two or three act like this. Do they just see me as one of the guys? Or is it possible they (one) might like me? If I did happen to like one of then how could I make it kinda known but not obvious? Do I come across flirty?
