A little late on the response here, but...
We've been asked this before and it's nearly impossible to track these girls after they leave AM. The ONLY way we know who they are is if they come up and tell us where they are working now. Usually, they either quit the business altogether or they go back to working for a Japanese shop, using some really common, cute Japanese girls name that makes it almost impossible to trace.
For the two you listed, we have no direct informaiton as to where they are now.
