And we don't even know if Raven waited a year or two after graduating Beacon to have Yang, so she could have been 22 or 23 when she had Yang. So, basically, Raven and Qrow are either almost 40 or are in their early 40s.

As for Winter and Weiss in the family portrait, I don't think Winter is 7 years older than Weiss. She could've been maybe 14 or so in the painting.
