6 week old kittens

We rescued a pregnant cat who now has three kittens. I should mention we have an inside kitty also. Mom and kittens stay in one room. The kittens are 6 weeks old. Two of them are eating dry food and one is not. Is this normal.

the third one, does he ates anything save the nursing? 

the problem usually solves itself for kittens with mom, as they are copying what the mom is eating, and also, their most daring littermate.

  If not, you can proceed to let him get  some manually, to "wake up" his interest.    Perhaps  Gerber stage one baby food...

Do learn them also to eat canned wet food.  so they do know what it is and like it too.
