The first to are really just two guns glued together, so I'd say the same rules for dual wielding apply.
Not really. If you pull the trigger on a double-barreled weapon, both rounds are going to the same place. You're not making two attacks, you're making one attack with two concurrent bullets.
I'd say it doubles recoil (because it's
literally doubling the recoil!) but on a successful attack, you resolve damage twice. That is not the same thing as doubling
damage, mind you, but resolving it as two separate attacks that land with the same successes.

As for the last one, I'd just say that a backpack hopper costs 50¥, holds 500 rounds, and counts as a single belt. Of course, you'd need a belt fed weapon, so just MGs, really.
It shouldn't be hard for a Shadowrunnian gunsmith to convert pretty much any weapon to belt feed, the question is if it's worth it.
