I feed my fish a pretty good variety of food. I feed pellets, flake and frozen. I would suggest some frozen food, some mysis or an emerald entree type cube. Bloodworms and brine are good too. The clown, damsel and gramma will eat all that I listed, at least mine do. LOL
And yep, wait a few weeks before adding any more fish, and if you have a test kit I would test for ammonia here and there to make sure you don't have a spike from adding so many fish at once to a new tank.

I have a mix of many different saltwater fish amongst my tanks, but I love my Tangs most of all.
