1. Aggi Nagy is Valentina Velasquez
2. In Die Anmacherinnen, Teil 1: Die Klassenfahrt and Die Anmacherinnen, Teil 2: Die Autopanne Dina Pearl is credited as Andrea Fejes and Julia Benvenuti (Julia Dobler) is the girl in the pics of Ivana Literakova. Then I think that the girl listed as Andrea Fejes can be conversely Ivana Literakova.
