The first season is Prisma Illya, the second is Prisma Illya 2wei (Zwei) - which is German for "Two" - the third is 2wei Herz (German for "soul" or "heart," apparently), and then Prisma Illya 3rei ("Drei," or three). Then comes the movie, which doesn't follow the pattern at all.
Amongst other possibilities . . .
