Deidara - One-Tail (obvious)

Sasori - Three-Tails (only logical assumption given it was Tobi's target, and he took over Sasori's spot). Not sure how that would've worked out though; Puppeteer vs. Water Monster (Somethin' to think about, but not really)

Hidan - Two-Tails (manga & anime)

Kakuzu - Seven-Tails (call it filler/non-canon all you want, that's not for anyone to decide as fact. Anime is part of the series & it's up the reader. Besides, it makes a lot of sense given their birthplace.)

Pain - Six Tails (manga & anime)

Konan - ??

Kisame - Four-Tails (manga & anime)

Itachi - Nine-Tails (that's been referenced multiple times in the manga)

Zetsu - He was a spy for the organization and didn't participate in the tailed beast captures.

Orochimaru - He was part of the organization, so his assignment had to have been either Eight-Tails or Five-Tails. The other would logically had to have been Konan's assignment.

Akatsuki decided to go after the Kurama last of all, because the Gedo Mazo would've collapsed if sealed it beforehand. Itachi apparently never had any real intention of capturing Naruto, otherwise he would have when Itachi crow genjutsu'd him in the forest to "talk". Hence, that assignment was passed around from Itachi to Deidara (Kazekage Rescue arc, which failed) to Pain. From the beginning though, Kurama was ITACHI's assignment. Before the start of part two (anime kinda messes up this part), it's logically deduced that the Five & Seven-Tails were already captured and sealed. That could mean, either A) Orochimaru defected before he could capture his target (this would imply that the Eight-Tails was his target), or B) Orochimaru's target was the Five-Tails and captured it. Konan's target had to have been either Five or Eight-Tails. Remember that Eight-Tails was given to Taka to handle because by the time they were to go after it, 5 Akatsuki members had died and remember we're not counting Zetsu. We already know what Pain & Kisame's assignments were. Konan & Orochimaru are the only ones left. Take your pick I suppose.
