OK. First judging standards for cichlids is less formal than that for dogs and horses mainly because cichlids represent 1000+ species. Still, all show characteristics that are 'ideal', based on the idealized specimen from the wild. Now for my personal opinion of your fish:
Adult male: I would judge him not show quality. He is too old - more like 2+ years old than 1 year old. His body (like my own body) shows signs of old age. The back area of the fish (not mine) has shrunk compare to the head. All of this is normal for older specimen. Color is just ok for a 4X Red Cac. It just has too much black in the pattern and more importantly the black on the caudal peduncle is 'disturbing'. This is atypical of this strain and probably is caused by some kind of nerve damage. Finnage is very poor. Front spines are too short (common in early reds, but rectified in better modern strains), tips of dorsal & anal fins too short, and the caudal fin is deformed. Compare it with this wild cac that is in my tank. I don't know its age but based on what I've bred in tanks and collected in the wild, I believe it was maybe 1 year old (that season's spawn). Note the shape of the body and length of the fins.
Of the 2 young males, I would consider the dominant male superior only because it shows a more symmetrical pattern in the caudal fin. It's too young to guess how his fins will develop, but they look promising for his age.
The female has good potential. The caudal pattern is pretty good - strong and symmetrical. The black on the dorsal and anal fins are different. It may be the photo, but the black pattern in the ventrals also appear assymetrical.
If these were my fish, I'd put the large male in a geriatric/community tank, breed the dominant male with the female, and keep the subdominant male as a back-up
