You can help support Chuchi in his role as 'alpha' but eventually, the pups will sort it out for themselves.
As another poster indicated, for now, and to help Chuchi adjust to the pups - treat him like the KING. Greet him first; feed him first; treat him first; up on the bed first; leash him first . . you get the picture. Let him know that he has not lost his status in your house. This will help him not be jealous. Try not to pay more attention to the new, little puppies, then you do to Chuchi. (I know this is hard).
Chuchi also needs a 'puppy free' zone where he can have some favorite toys or bones and not be bothered by young puppies constantly pestering him.
