I wanna have a make-up / make over party for my nieces this weekend. Ages 16/10/5?What can I do for them?

The one that is 16 wants to attract more guy in high school but doesnt know how so i want to show her how to doll up. she is not gurly gurl at all and is not your typical gurl. she is into anime (which i am to) and drawling and thats really all I know about here. She doesnt play sport or do much of anything in high school. We are totally different. When i was in school i was wild n' out all the time and doing things i should have not been doing so i dont really know how to tell here how to approch a guy/gal(yes she likes gurls) in school. But anyways i jusrt wanna have a slumber party for all of them. I wanna rent some movies and cook fun snacks and just do gurly things .Well anyways thanks for your help everyone.
