Hey baby? why did he say this? i dont even know them?

Girl, you are just a baby. Don't let these upper clmen put stuff in your head. "Hey baby?" If they were decent, the least they could do is learn your name if they liked you. They seem like trouble and i would advise you to ignore these boys and find nice boys your own age. At your age, this may seem exciting. Trust me when i was 15 an 18 year old guy was after me. I thought I was so cool. But you know what? They are only after one thing....don't waste it on someone stupid.
