How do you say hello all in Hawaiian?

"Aloha kakahiaka" is the most common way to say "hello all" in Hawaiian. This translates to "good morning all".

Here are some other options depending on the context:

* Aloha kākou: This is a more general greeting that can be used for hello or goodbye, and is appropriate for a group.

* Aloha mai kākou: This means "hello to all of you".

* E komo mai: This means "welcome in" and is a good greeting for welcoming a group into a place or event.

It's worth noting that "Aloha" alone is a widely used and accepted greeting in Hawaiian, and can be used for hello, goodbye, and even a simple expression of affection.
