Other members or Rosen Kruez
1 Cain Nightlord (Mein Herr Contra Mundi)
2 Isaak Fernand von Kämpfer (Panzer Magier)
3 Dietrich von Lohengrin (Marionettenspieler)
4 Radu Barvon (Baron of Luxor, Flamberg/Flame Sword) though I dont know if you can count him since he was already dead and just a puppet being used my Dietrich.
If thats the case what happened to the other 3-4 members of the Rosen Kruez Organization?
