Weapon ideas for the Toa:
Tahu could have a Broadsword with a design similar to his 2001 Sword.
Gali can have her hooks, but instead of looking like her 2001 hooks, I feel they should look like the Maori style of fish hook. (Think like the giant hook Maui has in Moana, if any of you have seen that.)
Lewa.... I got nothin (you guys can brainstorm on hers)
Kopaka's weapon will probably be a longsword, along with a shield because it's Kopaka. It makes sense to me that if Tahu and Kopaka are opposites, they're weapons and how they fight reflect that. A Broadsword weighed around 5 pounds, and had a Wider blade than the longsword. It sacrificed reach for damage, similar to Tahu. He didn't care about things like reach, he saw dealing the most amount of damage as what mattered. On the other hand, Longswords weighed twice as much as a Broadsword, which meant they had to be held with both hands. They also had tremendously long reach. Similar to Kopaka, the user had to plan out every single move they were going to make, because the added weight would make it a lot harder to attack again quickly if you missed.
Can't think of anything for Onua either... same with Pohatu....
Well, for the ones I did give ideas on, tell me what you think?
