In season 5 in the episode "The Day the Magic Died", Piper gave birth to their first son, Wyatt. In season 6 in the episode "It's Bad, Bad, Bad World Part 2" she gave birth to their second son Chris. In the series/ season 8 finale, "Forever Charmed" when Piper is taking her turn to write in the Book of Shadows, it shows her with her two sons as well as a daughter, that is assumed to be Melinda, the daughter she saw she would have in season 2 in the episode "Mortality Bites".
So Piper and Leo had two sons and theoretically one daughter that really only exists in a future beyond the show.

Forever Charmed, the series finale
If by 'girls kids' you mean Piper Halliwells (and Leo Wyatt) kids, the oldest is called Wyatt (Leo's second name), and the younger one Chris (after Leo's Dad). Hope this helped:)
