And the six princesses in question, from left to right, are:  Anna,  Chream (not sure how to spell her name, but it seems to be based off "cream"), Chocoletta,  Biscuit,  Maron, and  Maplille (once again I'm not entirely sure of how to spell her name, but it's apparently a pun on "maple", as in maple syrup).
