In West central dialects ye (you) has distinct plural yiz [youse may be more emphatic], a possible import from Ireland. This is so useful it seems to be becoming a standard, replacing the ye [you] plural
Whit’re yez daein the nicht? What are you (all) doing tonight?
An informal American English equivalent would be ‘y’all’ or ‘you guys’. Further emphasis can be provided by you(se) yins.
