Saw a different spoiler, which has a picture of a bunch of the Devils that have worked with Makima, and holy shit, the translations got the names all wrong.
They're the names of types of angels. In addition to "Angel" himself being obvious, for example, "Beam", was "Bim", as in "Cherubim". "Prinz" was actually "Princi", short for "Principality", etc. "Power" is also a rank of angel.
It's amazing how it was right in front of our faces the whole time, but by keeping them separate, it was less obvious.
EDIT: More text spoilers:
8 servants arrive at Makima's home, kneeling They were all waiting to be revived on this day. Kishibe orders Makima's headquaters bombed, and snipers fire relentlessly on Makima 5 of Kishibe's own men cut off their heads and summon the hell Devil to kill Makima and send her to hell
