I am a 16 year old male teen that is 127 lbs and is 5''9 tall, do any of you think i should gain weight? and what would be a more healthy weight?

Well, I busted out the handy dandy bmi calculator thing, which can be found here:

And you are at a healthy weight mr~! You don't need to gain weight unless you'd like to, in which case a healthy weight range for you would 124-164 pounds. :D
