Is it permissible to name a girl after the wives and daughters of Prophet Ayyub (peace be upon him), even if these names are not confirmed in the Prophetic Sunnah?

There is no legal impediment to naming a child after Ayyub's wife (peace be upon him) or his daughters; for any name free from legal prohibitions is permissible. The exegetes mentioned that Ayyub's wife's name was "Rahma," and it was also said: "Liya." No information has been reported regarding his daughters' names.
