Kisame: Has way too much chakra for Kakashi to handle
Itachi: Do I really need to explain?

Kakuzu: Will beat him if its 1v1 as he almost did if Naruto was not there
Konan: From what she did to Tobi I think she can hold her own.
Zetzu: This is kind of iffy because if Zetzu has thousands of clones to his dispersal then he wins
