The Damsels will fight (that includes the percula clown).
As for the tang, butterfly, and puffer they will go together pretty well, however,
Tangs are bad when it comes to getting ick, so always quarantine a tang before introducing into the main tank. They give your tank an excellent splash of color.
Copperband butterfly fish do not have a good survival rate. Some will adapt well, and then some will die within days. So make sure you get a healthy one. They are very beautiful though.
, is the hardiest fish in your list (besides the damsels) they are susceptible to ick but not as bad as Tangs. They have great personalities.
Hope this helps.
