You're referencing to Anya, who was not a commander. She had the same or similar status as Indra now, who is the chief of TonDC.

As of 3x09 it's revealed Luna is the 8th Nightblood. It's uncertain how Luna is connected to Lexa (why Lexa didn't kill her).

We also don't know just how Costia got captured, but we do know she was killed because of her connection with Lexa.
