From Kiril's commentary the Clockwork Lullaby album:

''Thanks to the “Re_Birthday” time wound back.

And so Irina will once more become Adam's…

And Eve’s mother.''

We're not really sure how to interpret this statement other than Maria being Adam Moonlit and Eve Zvezda's mother. As said before, the Re_birthday appears to have brought everyone back to the original incarnations (Irina becoming Maria).

Also, while there have been instances where irregulars are irregulars in their reincarnations (Ney, Kokutan) there are also instances where they aren't (Rin Miroku, Lilith). So, the twins Adam and Eve could have become Maria's twin children, then died and reincarnated as Adam Moonlit and Eve Zvezda.

Also, to address your other point, Adam Moonlit is 17 by Project Ma, and the Heavenly novel states Maria gave birth to and fled with her twins "ten-odd years" before Project Ma, so there's a bit of leeway there.
