Saying "No!" to the dog is not going to help the situation, as you can probably tell by now. 
The dog thinks you are barking, so he's going to start barking back. Its a play thing. He'll explain it to you when he's older.

Therefore, stop using "No." I advise my clients that "no" has no meaning to a dog other than to sound like you are barking. They do not understand it and it is used so much in every day speech that the dog can't associate it with much of anything.
You must learn to ignore your dog. When the dog is trying to engage you in play or whatever, and you are busy, you must ignore the dog completely, no eye contact, no petting, no words, no nothing. Ignore the dog until he stops the unwanted behavior. Even if it means going into another room and shutting the door (always very effective because they thrive on attention), you can't give in to the dog.
Once the dog has calmed down and is exhibiting proper behavior, you can reward the dog by playing with him, rewarding him with a toy or game, a treat, or a walk or whatever.
So stop barking at your dog and he'll stop barking at you!
Good luck.
