First of the ones we know: Deidara - One-Tail; Obito/Sasori - Three-Tails; Kisame - Four-Tails; Nagato - Six-Tails.

The ones left are: Two-Tails, Five-Tails, Seven-Tails, Eight-Tails & Nine-Tails

We know Hidan & Kakuzu clashed against the Two-Tails. And in my opinion it was Hidans Tailed Beast, he prayed for forgiveness because of not killing his opponent.

Hidan - Two-Tails

Which leaves Kakuzu - Seven-Tails

Taka was responsible for the Eight-Tails because of killing Itachi, so...

Itachi - Eight-Tails

Nagato captured the Six-Tails which makes = Konan - Nine-Tails

The only one left is Five-Tails and the remaining Akatsuki Member are Orochimaru & Zertsu.

Because of Zetsu not being a front-fighter makes Orochimaru = Five-Tails.
