Depends..........
There's no 'right' weight for anyone, but depending on the body type the boy has, he could range between 100 lbs - 160 lbs. Again, I say there's no right weight, so if he is over or under, it's nothing to worry about.
Weight is worked out on height not age.

Definitely. He is right in the middle of the "Healthy" range mostly because he is tall and his weight is well distributed.
