Bob Goemans has a nice section on his website that could come in handy for you:
Welcome to Saltcorner.
When it comes to Centropyge angelfish, Bob only has 3 species that he recommends for a reef environment. They are the Coral Beauty, Half Black, and Flame. I have never kept a Flame Angel at home, but I plan to take Bob's advice on the subject and put one into my 180. From what I can tell, he is very conservative in his recommendations.
I agree with Cody's comments above on all other selections. I think you are pushing the limits with most of these suggestions. Keeping 3 Clownfish is rarely advisable. Keeping a Mandarine in a small aquarium is generally a receipe for disaster. (Yes, a 40 is small.) Chromis rarely work well in small groups and generally only are kept successfully long term in groups of 20+ in very large tanks.
I think you still have a lot of planning to do. In the marine hobby, you have to sacrifice personal interest in favor of what works best for the fish. Sometimes that means waiting until the "next" tank for the species you really want.
