You people

Alley cats

Pal, bud, friendo, sport, tiger, chief, boss.

Y'all Y'uns Fuckers

Dudes is fine - folks and yall also work. I use yall all the time even though I'm now in Canada and have never lived in the US south.

Guys, I think, is still a bit too gender associated but it's borderline. Man is often used in a gender neutral manner but it is very easy to misinterpret and a transwoman could reasonably assume you're trying to troll them.

You've also got fella and feller, I think the latter one is more gender neutral than the former.

What I use is y'all or folks for plural, and dude for singular.
