I'd actually say that Rossweisse is 21-22 by now.

She went to school in Asgard, and her life was purely academic, so it's likely that she skipped some grades, or finished them faster.

Also, we shouldn't judge "supernatural" schools by the same standards as human schools. So saying that you get a masters degree at age 24 might not apply to supernatural characters who went to supernatural schools.

We do know that Rossweise was at least 20 by the time of vol. 9, since she was drinking alcohol with Azazel (the legal age in Japan is 20). Rossweisse is a rule/law-abiding person, so she wouldn't drink alcohol if she was under-aged, even if someone provoked her.

As for Vali, we found out in vol. 21 -- Encounter White Dragon and Black Angel, That Azazel found Vali 7 years before the start of the series. And in the series Slash Dog, Vali (who has been with Grigori for at least a year by now) was 12-13, and Tobio was a first or second-year in high school (could you guys please confirm which?).

Considering all of this, Vali should be 18 or 19 by now.
