Yes
Gauge indicates a shotgun, not a rifle. The 8 gauge has been out of production for many years, and was a black powder shotshell. The 8 g. is not legal for hunting in the US.
Any true 8ga gun is rare, and should be carefully evaluated by a competent gunsmith. Would bring at least several hundred dollars, if not over a thousand.
18ga thru 8ga depending on the circuit it's being utilized in.
12ga is 2mm and 16ga is 1.2mm so it would be 3.2mm. 8ga is 3mm so that'd be the closest size. However using two rings to stretch doesnt give the ideal stretch because it can be uneven. And theres a chance that it wont be exactly 8ga since it's an uneven stretch.
It is a shotgun
There is no restriction on different size wires being spliced in the same junction box. If your question involves splicing 8ga. to 10ga, this also is not a problem so long as the circuit allows for 10ga wire.
