As I said, I don't think stocking is a simple question. It depends on where the fish lives and what it eats. You have three fish that live mid water. In a 30, to my mind that is too much. I divide the tank into sections. First, open water fish and in rock fish. Then I look at the level they live in: Top level, mid level, and then lower level (in a breeder I only look at mid and bottom. There are very few actual top layer marine fish for aquaria). Each level and area has to be looked at differently and needs to be stocked specifically for that area. You can have an overstocked area, and still have an understocked tank for instance.
After that you have to look at food, and where that food comes from. Does the fish have a utility role in the tank that reduces bio load? Does it complete for food from the tank with other fish or is it a decorative fish where it's primary nutrition comes from you feeding or does it mostly eat things inside the tank and only need supplemental feeding? All that is a stocking question that has to be answered after you figure out what area the fish lives in.
As I said, not a simple question. In your case I would say that you have your mid level, open water area over stocked, your mid level, in-rock area contains a wrasse and the rest have no stocking at all.
That is just my view on it of course.
