Alright, let's see what the drinking tollerence is.

Aoi: light weight. Two mugs and She's down.

Ginger: can hold up to ten drinks. Then she's gone.

Aka: she's a little over Ginger's limit. By one.

Ki: on par with Zoro.

Aisuru: You're talking about the daughter of Shanks here. She can probably drink just as much as her father if not a little under.

Yatsumi: completely on par with Shanks. I'd be afraid of a drinking competition between the two.
