I think a doctor would better be able to determine that. They would know your bone structure and all that stuff including your activity level and how many calories you should consume daily based on that n other things.
At 5' 2" and 19, without knowing any specifics about you, I'll guess 105-115 lbs.2

That depends on your frame size, muscle mass, etc.
I'm 5'2" and 105, and I have a tiny frame, I'm not particularly muscular, so I look about right.
But 105 on you may look super thin.1
