As far as weight goes they both sound a healthy weight to me.
Boxer pups have a way of growing in their own individual way so it's hard to say whether or not a pup is of "normal" weight, but as I said they sound healthy to me.

Just on another note, how much running are you doing with your pup?
A lot of people recommend limiting "forced" exercise particularly until a pup is closer to being fully developed.
Forced exercise, particularly on hard surfaces, can be detrimental to a growing pups bones & joints.
Might be something you want to look further into.
