I don't know your biological sex so that makes it hard to say and I'm an old woman so forgive my not knowing the proper gender terms to use.
1) possibly a little if you're a bio-male but one never knows
2) sorry, if I knew that I'd be a rich woman
3) maybe, maybe not... If you're a bio-female, generally your full height is attained about 2 years after your first period. If you're a bio-male, you usually grow until you're at least 18.
Chin up though, way back at the dawn of time when I was in school, I had a typing class. (Yes, on typewriters, as there were only 5 TRS-80s to be shared in the computer lab. As I said, I'm old.) John say next to me. John was the shortest guy in our sophomore class and had been pretty much as long as it's known him. He was about your height when our sophomore year started and then by the end of the school year, John was 6'4" tall and one of the tallest boys in our class if not the tallest. Do I think you're going to be 6'4"? Probably not but it's far from over... Nil desperandum.
