If I remember correctly, it was said in volume 1:

There were 100 rings all in all, with 42 of them already taken. Mare took the 43th and Albedo took the 44th. But Ainz had another motive when giving the last 2 rings as explained in the novel. He's paranoid after all.

Akemi could have been using the ring just to teleport directly to the 9th floor instead of going through all the floors on foot everytime she visited her sister.
