These maidens (including Jill) appear in Shrek 2. Maiden #1 is blonde and Maiden #2 is brunette. Jill is also one of the maidens, but unlike the others her name is given.
Shrek 2
Shrek wakes up in the barn in his new human form, finding himself surrounded by the maidens. They are all taken by Shrek's handsome physique, flirting with him and competing for his attention. They find Puss to be cute as well, but are put off by Donkey's (who is now a stallion) neurotic behavior. Puss tells Shrek that he needs to kiss his true love before midnight to remain human. The three all say that they'll be Shrek's true love, with Maiden #2 adding that she'll be "true enough" (suggesting that she is promiscuous). They pucker their lips to try and kiss Shrek, but he disappoints them by saying that he already has a true love. They are last seen after Donkey suggests to Shrek that he needs to change his clothes, causing the maidens to gasp in excitement.
