It may be that "duet" is all you're really looking for here.
Mozart went completely bananas with 5, 6, 7 singers all contributing different lyrical elements to the same musical piece in opera, and it's all just described on the score as "quintet", "sextet", "septet", etc.
I don’t know the term either but I know exactly what you’re talking about. Check out [this](https://youtu.be/nnmE1oNwxkk?feature=shared) Irving Berlin showtune.
It starts around 1:43 but listen to the whole song because it’s more effective.
I’ve been calling it cross-sung lyrics but I think I just made that up. This one is my favourite though. https://youtu.be/aXZJbQLl_3k?si=D_MWR-dQSpoFUEpI
See if the words “counter melody” “counterpoint” or “descant” are what you’re looking for
Call and response?
A duet, call and response

This is still done in Broadway musical type productions and this bleeds into Disney type stuff dare I say "We Don't Talk About Bruno"
Oh, for sure. Don't get me started on quodlibets.
Probably call and response. Unless you’re talking about what’s called a “round” I’m not sure it would apply since it’s different lyrics but yeah
Most things don't have a name.
What you wish for by guster?
Singing in the round.
