Also just got dupe German Iris on a 11x roll.

If you just started the game you might get some value from lvling them a bit but to be honest it's better just to merge them into your main girl of the same name until you have 5 skill and 4 equip unlocked. 5* come thick and fast, there are 5 on perma reissue and another on reissue plus the current event girl and they add a new event and a new reissue every 2 weeks so you should get 20+ 5* very soon and not need any dupes.
