Before I begin, you must understand that our local standards are far worse than yours. Here goes:
Show fish must have straight and neat everything. Fish #1 has thin and folded caudal and dorsal, and long anal. The edges of his fins are not neat. His pectorals aren't aligned.
Out of the yellow, I prefer #4 though the top part of his caudal looks as if it has been bitten. His dorsal and anal are at least straight, if not leaning forward. He has nice pectorals too, though I'm not sure if they're aligned or not.
