Im 16 and i do have a little facial hair.. does this mean that i stopped growing?? note:iam taller than my dad whos 5'5 nd im 5'7

No. You r still: growing and could continue to about age 21.

Hard to say: You can grow taller until the growth centers in your bones close. An x-ray of your wrist/hand can be examined for these growth centers. If they are open you can grow taller, if they have closed you are finished. Men usually continue until 16-18. Men are expected to reach the average of both parents height plus 2.5 in.
