The best thing would be to wait until it flowers and take high-quality pics of them (close-up, side, top, full, etc.) Cactus ID is pretty tricky since many are able to hybridize with eachother.

The one on the left is A stapleia, probably gigantea. Its difficult to ID without a flower, but my asclepiad expert sister said most likely a gigantea. The one on the right is haworthia. Probably some hybrid of coarctata.

k, It's certainly one of the more uncommon Kalanchoes available - lucky you. Kalanchoes and Jades (Crassula ovata) are in the same plant family, the Crassulaceae. And then there's the whole 'plants of the Arabian Peninsula and nearby islands' that never fails to weaken my knees.

I don't think that last one is RED RIBBONS. RR is a spider, and the sepals on yours look too wide. But it could well be the angle of the shot. Maybe if you could take another picture? I'm not sure what "Sommerbee Akron D" means, but I searched the AHS website for "Akron," and nothing came up that could be your NOID. Ditto for "Sommerbee": no hits at all. The first one looks familiar somehow, but no name or hybridizer name is coming to me. Maybe someone else can ID them for you. It's so frustrating to have NOIDS, so you have my sympathy!
