I agree with the above. Some chins simply don't get along, but there are degrees. If this male of yours was kacking and going after and biting the other chins he was put with, then I'd say no, don't try to get him to get along with others. If it was the other chins that didn't like him, then I might give it a shot. If at any point he drew blood from another chin, then for me, we'd never put that chin in with another chin.
As for age playing a role in chin bonding -- I can say that the younger you try to introduce, typically the easier it is. That said, I've had a 9 week old kit decide to chase around my adults when intro'd to them. Needless to say, he became an only-chin. With that said, one of the latest pairs we adopted out were two 8 year old chinchillas. One chin had been a breeder of ours and had been caged with other chins before, the other chin never had a buddy in her entire 8 years. The two of them got along fine and absolutely adore each other. So I think it depends more on the personality of the chins than specifically on age.
