The Straw Hats and Haki, huh? Well, Luffy can use all 3 kinds, Sanji and Zoro can use both Busoshoku and Kenbunshoku and Usopp just developed Kenbunshoku. Who's left?

Nami and Robin may or may not get Kenbunshoku as well because apparently anyone and their mom can learn it. I just don't see them using Busoshoku.

Chopper is an animal so 1. it's questionable if he can even use Haki and 2. if anything he should develop Busoshoku since his nose + instincts + Rumble Ball make Kenbunshoku kind of redundant.

I'm pretty sure Franky could build or has already build some kind of sensors into his latest body model. And he's made of freaking metal so his character doesn't have any use for either of the two common Haki types.

As for Brook, the question is: can you still develop Haki when you are (un)dead? IF so I'd say he's a candidate for both types. Then again, doesn't his soul ability make Kenbunshoku redundant? And does adding Busoshoku to his attacks make any sense?
