I suppose that space-wise they would fit in there, but I'm not sure about combining angels with gouramis. Sometimes it works, sometimes it doesn't. I haven't kept pearl or dwarf gouramis myself, but I've heard they can be a bit nervous and shy, and if that's true it doesn't exactly help. The shark might stress them too.
By the way, I suggest you remove the clown loach you have. Not only are clown loaches social fish that want groups of three or more, but a 35 gal is too small for them since they can reach 12 inches in the wild and up to 8 inches in an aquarium.
