I'm 15 almost 16 and this is my measurements 32-25-36 in inches is it OK? I'm 5'2'' and I weigh 116 lbs. My BMI is 21.5 am I fat?

You are far from fat, 116 lb 5'2 is normal weight-height ratio. Don't worry about what society places you in, the important thing is that you feel fit and happy. Skinny, fat, or normal everybody needs an exercise program.
