I would put the rabbits on a scale if you want an accurate weight...rabbits are unusually hard to eyeball because of their light skeletons. Meat rabbits can be oversized for the breed or mixed with other breeds to make them larger and faster growers, so you want to get your hands on your rabbits and feel along them to test for fitness. Unless you have a particularly boney breed (many lines of English lops and some agility breeds in particular), the spine should not feel sharp but should be rounded yet clearly felt, and you should be able to feel the ribs with nothing more than a *slight* layering of fat over them. This works for most breeds:

Common problems with obesity include strokes in rabbits (more prone to them than most), bumblefoot, digestive issues, pregnancy issues, etc. Pregnant/lactating does are generally free fed pellets though.
The only people I personally know who eat angora meat are those who raise French angoras, and who raise them to be multi-purpose. Even though they have more to their loin than other angora breeds, you are still looking at a higher bone to meat ratio than you would find in other meat breeds. The meat is said to be very good though. Most people however, do not want to deal with the extra coat care and wool block issues that come with angoras, and even those who raise the French for eating generally only eat their culls. But, no harm in trying. I could never eat an angora myself though because they are so darn friendly! XD
Your buck looks to me to be a non-show line French or (less likely due to fur growth pattern) a mix. He looks to be a black tort, but I am the worst person ever at coat colors. Ever.
Good luck with your rabbits!
