The sohal tang will get way too large and aggressive for that size tank, and clowns don't generally tolerate other clown species in the same tank, I'd guess the maroon will kill the occellaris at some point.
Also, alot of pseudochromis species can get very aggressive but I'm not familiar with what species a "strawberry pseudochromis" is.
The rest looks fine, I'd introduce the 2 zebrasoma species at the same time.
