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.
4 year old girl
Definitely. He is right in the middle of the "Healthy" range mostly because he is tall and his weight is well distributed.
A 14 year old boy with a BMI of 23.5 would be considered to be in the healthy weight range.
