Juugo, Karin and Sasuke will most likely drown from Kisame's water bubble, if it comes down to that.
And Suigetsu is clearly not on the level of Kisame, and will be killed.
Even if it doesn't come down to the water bubble, i think that Hebi would still lose.
Samehada really seals the deal here, stealing chakra from people who already don't have that much chakra.
Juugo, Karin and Suigetsu would all be easy pray for Kisame, and when it comes down to Hebi Sasuke, he will most likely lose.
Unless he keeps flying around like a scaredy-cat.
Not sure how much of a factor Chidori will be here.
I think that if Sasuke uses his Chidori lance he might as well murder Samehada and win because there isn't enough water around for Kisame to use any large scale techniques.
