1. Daikodan is a Suiton, so it gets absorbed. Simple as that. Even if it'd counter Preta Path like Mokuryu did, Shinra Tensei would easily repel and dispel it, so its not a factor here.
2. Bansho Tennin attracts Kisame right to Nagato and he wraps him up nice and tight with Asura Path's mechanical limbs and absorbs enough chakra from him via Preta Path that he can't do anything. Or he riddles Kisame with black rods, preventing him from even moving due to Nagato's chakra paralyzing him.
None of Kisame's moves are even a factor considering they all use chakra, Deva path and Animal Path's bird pretty much screw him over regardless of his advantage.
Like I said, Nagato stomps, shouldn't even be a question.
