Here are some options you could use, depending on the context:
Formal:
* E nā wahine a me nā kāne: This literally translates to "Oh women and men," and is a respectful and formal way to address a group.
* E nā makamaka: This means "Oh friends" and is a less formal but still polite way to address a group.
Informal:
* E nā hoa: This means "Oh friends" and is a casual way to address a group.
Alternative:
* You could simply address the women first and then the men, using the appropriate Hawaiian terms: E nā wahine, e nā kāne.
Ultimately, the best way to address a group in Hawaiian depends on the specific situation and the level of formality desired.
