The show has introduced us to "angels" since the beginning, in the forms of Michael (Burnham) and Gabriel (Lorca). And arguably Airiam (Ariel). A post above brings up the Control/Uraei connection, which leads me to think more of the Archangel Uriel, although that's a very tenuous connection reliant on a novel.
I went through the Wikipedia list of Angels to see if I recognize any other names. There's a Daniel, which makes me think of Daniels, but even though he's a time traveller from the future, he's an Enterprise character and the name is coincidence.
There's no angel named Amanda or Zora. Paul is a famous Saint, of course, although he was named after a real world mycologist. Sylvia (Silvia) was a Roman goddess, and a version of her was the mother of Romulus and Remus, but this is diving too deeply into unintended etymology.
I think the clues for an angel connection lie with the three main crew: Michael, Gabriel, and Airiam, and no one else. This implies that a version of the Red Angel may have been in the making since Fuller, although it's more likely he was just being poetic and the Red Angel is a retroactive connection.
Michael is a woman and the main character and has been discussed. She would have a vested interest in saving herself, and have of course been a witness to much of the "Angelic" activity.
Gabriel Lorca is a tougher pill to swallow. He's not a woman (although the Escape Artist explicitly showed the ability to hide one's body shape in an exosuit), and his mirror 'verse version was shown to be disintegrated. It would be a bit of a mind twist for the Prime Lorca to be the Angel this whole time (and would require explanation), and even moreso for the Mirror Lorca to have that position (back to life a la Culber?).
Airiam appears to be an upcoming antagonist, and possibly "infected" by the Red Angel or the Red Angel's opponent. She was my main choice a couple weeks ago, but I think she's more of a Red Herring, after this week and the preview. She might be *a* Red Angel (if there are multiples and it's a group), but not *the* Red Angel (if it's one person).
