Looking at the new forces of evil. I think their rank and more likely power is linked to the number of black stars in their body. Both Utena and the veteran leader have the same number of stars.
I am not sure how many stars Kiwi has but Korisu has three.
Update: I was looking at the earlier chapters where Kiwi was introduced, and she does not have any stars in the front of her body nor her back. Maybe these stars are on her shoulders or in the lower parts of her legs.
Depending on how you count them, Utena may have more, with one on each of her eyes, cheeks, and horns giving her a total of Six to the new girl's 4 on her forehead.
The one with three also have some earrings though, making her number up to 5.
