Yeah, they're from DMM. Some are new classes you probably won't recognize unless you play the game at DMM or wait until Nutaku gets them.
1st row: She who will not be named (as he still wishes her event hadn't been skipped) but if you really want to know
3rd row: Erenia (plat dragon rider) - Sandra (plat swordmaster event unit)
4th row: Ehrett (gold priestess warrior) - Laurier (gold druid) - Eln (gold angel from TP) - Alice (black monk)
