Yes, though it is an uncertain thing, but in general, I believe that they do. Arthritis that comes with age causes the bones to ache, and maybe even to swell, and I believe that the knuckles are not an exception.
Whether certain people's knuckles swell/grow larger is relative one's personal lifestyle, but cracking them may very well increase the size of your knuckles later on, if not just hasten the arthritis in them alone.
Some people say that it can cause arthritis, but this is untrue. Cracking your knuckles can cause your knuckles to grow larger though.
Yes in sonic heroes, the manual that gave all of the information about the characters said," sonic the hedgehog, age:15. Knuckles the echidna, age:16, so yes knuckles is older than sonic

No bats do not have knuckles, they have no hands, so therefore no knuckles.

NO! Popping your knuckels just pushes the joint out and back into its normal postition. The sound that comes from popping them comes from the gas of the fluid that is between the bones as they are poppin in the fluid. It wont make your knuckles larger, but you might make your grip weaker if you do it too much cause it can start causing problems, such as arthritis.
