There is one ok piece of evidence (from the anime I'm not up to date on the manga) that says she cannot remember who she turns into a toy or even whether she did so. There is, however, even better evidence that she could communicate to her non-remembering self and turn him back. I am not aware of any evidence that she could turn someone back at will but that is comparitively trivial as I don't believe (though they may I just don't see it) that they age while they are toys.
At the start of the arc, she had reportedly only ever let one toy free without a contract (Kyros). She does the religously every time she uses her power (could be anytime she sees a new toy randomly appear in front of her). When Robin is turned into a ragdoll, she makes no contract and does not try to find her to make one while Usoland is running away in terror. If she can remember, this could also be an oversight on her part, knowledge that she can't get to the toy in time anyways, or may be even an oversight by the animators (couldn't possibly be one by Oda...that is impossible). If she could not remember Robin, this makes perfect sense and she would behave exactly like she did.
Whether she can remember or not, the statue of Kyros has stood since before he became a toy and communicates information such as his name. The Toyfamino being contractually ordered to serve himself has free will and can walk her through whatever he needs (as long as he can get her to believe him for a second. He cannot be the last of his "family" to be turned into a toy, however, or she would give him a different contract.
This all assumes, however, that she is loyal to him. For a young? lady under constant guard by as slimey man she is constantly ordering to die, this might be a radical assumption. Whether she is loyal or not if he does not age as a toy, has free will, and she will someday die (if he has to kill her to do it), he will likely survive the incident without being physically harmed.
