Here are some options:
* ʻOhana: This means "family" but can also encompass a close circle of friends considered like family.
* Kānaka: This is a general term for "person" but can be used to refer to a close friend, especially someone who is like a brother or sister.
* Hoaloha: This is the closest translation to "friend" but is often used for someone you are very close to, a best friend.
* Hoa: This means "companion" or "associate" and can be used for a casual friend.
Ultimately, the best way to express "friend" in Hawaiian depends on the specific relationship.
