Aureole Omega is the youngest but the leader of the 7 sisters. If you go with Greek letter then Entoma probably the younger sister vs Shizu. However Narberal Gamma and Solution Epsilon are treated as a "pair of twin" so they are treated as 3rd oldest thus the seniority between battle maids doesn't use Greek letter designation. Aizn said that he doesn't know who is the younger between Shizu and Entoma, so we have something like this:

"Age"

Yuri > L upusgenia > Narberal = Solution > Shizu ~ Entoma > Aureole

Authority of 7 sisters

Leader: Aureole

2nd in command: Yuri

Authority of 6 stars

Leader: Sebas

2nd in command : Yuri
