These terms are used a bit inconsistently, but what I'm answering here should be fairly uniform across a lot of the English-speaking community.

OVA and OAV are synonymous. The reason for having two acronyms is historical; currently, both Japan and English-speaking countries use "OVA" as the official designation.

That is: a "character song" is a song whose vocals are credited to the ...

There's no strict ...

This is purely conjecture. I suspect that flags are effectively the same as booleans in computer programming which can have values of either true or false.
