Hypothesis:

2nd tier - 1 Angel (10 lv)

3rd tier - 1 Archangel  (20 lv) or 2 previous one.

4th tier - 1 Principality  (30 lv)   or 2 previous one.

5th tier - 1 Powers  (40 lv)   or 2 previous one.

6th tier - 1 Virtues  (50 lv)   or 2 previous one.

7th tier - 1 Dominion  (60lv)   or 2 previous one.

8th tier - 1 Ophanims  (70 lv)   or 2 previous one.

9th tier - 1 Cherubims  (80 lv)   or 2 previous one.

10th tier - 1 Seraphims  (90 lv)   or 2 previous one.

Super Tier - Multiple examples of the previous ones through the pantheon spell. In the case shown by the LN: 6  Cherubims  (maybe it is possible 3 Seraphins or 9 Ophanims?)

Neia said in volume 12 that it is possible to summon more than one monster if a higher-level spell is cast. But is rare.
