How much hair is normal for a 15 year old asian girl.?

I have a friend who is fair/normal with black hair. SHe is worried about the hair on her body. Her eyebrows ar thin naturally, she plucks one or two hairs off her chin and she does her mustache once every one or two weeks. The hair there is not very thick but can be seen at the sides.Till half of her cheeks she has some thin but long hair and because of her fairness it can be seen sometimes. On her chest she has small thin hair , on her stmach and back though it is a bit thicker and can be seen. Its not coarse and BLACK but its thin hair but there quite alot of it - especially down the middle and so it can be seen alot. Even the area under her neck on her back has hair so she dusnt wear low backs. Its not too bad but ykno its not completly clear either. When she shaves her undrarms in the mornig, the nxt day u can see small black dots - not hair but u can tell its started growing so she has to shave every second day. On her arms and legs al the way up and down she has hair. Is that ok?
