Non-twin, Brother and Sister, one born close to the start of the school year, one close to the end. assuming gestation in remnant takes less than a remnant year as in real life for earth year. This allows them to be siblings but not twins, without either getting moved ahead or held behind.

Twins. The current go-to theory I suppose.

Half-siblings Mark 1, Version 1: Born less than a year apart to different mothers. Their father is a bit of a Man-Ho? Allows for them to be raised as siblings but not as twins, with one definitely defined as the 'older sibling'.

Half-Siblings Mark 1, Version 2: not twins, Less than a year apart, but as they Share the same mother, different Fathers, obviously not long after the eldest was born, their mother got pregnant again. Maybe the first father was gone? (Parallels and Mirrors Ruby and Yang's parental situation?)

Half-Siblings Mark 2, Version 1: Born close enough to be considered twins, raised as such, though they are born to different mothers. older/younger regardless of known truth generally applied in the way that pop culture says about twins arguing over the issue (ie.e. 'hey, you were only born an HOUR after I was!').

Half-Siblings, Mark 2, Version 2: Born as twins, to the same mother, but DIFFERENT FATHERS. Maybe not even known to 'their' father.

Full or Half Siblings, but more than a year apart. One was held back, or one was moved forward. If this, I like the idea of Qrow being the younger moved forward.

They dont HAVE to be siblings, though. They could be Cousins, or Uncle/Niece wherein Qrow was just born really late (I have an uncle who is YOUNGER than I. I'm in my twenties, and my dad's in his fifties. But if we had attended the same school, we'd have been in the same year group. I in may, he was born in june. Or July. One of those two.)

My Headcanon on this issue:

They're Half-siblings, (Paralleling R/Y) Raven is younger, (Match to Yang, Mirroring R/Y) by a year (Different from R/Y). The two wouldn't have ended up in the same year, the same Team (Parallel) However for whatever reason, Qrow was Held Back (mirror) but already had experience as he'd previously been on a team (Different.) Something parallel-or-Mirror to do with, though neither are made team leader (Mirror Or Different?), something Parallel-yet-different. Bah. Can't think for that :P Also, to keep with the whole 'four' thing, someone new or removed versus Ruby and Yang.
