"you all" or "youse" can work as reasonable alternatives. I haven't tried "tons" since I've never actually heard it "used in anger."

One less fraught, but equally confusing terms are "a couple" vs. "a few" vs. "a handful" (some believe "couple" = 2 whereas others treat it and the others as explicitly more fuzzy). Often it's best to just assume as little context as possible and be a little more explicit and verbose.
