Answer 1

You can try something like:

a:A{a.name == b.name, a.date == b.date} # b:@B{ -> b.index = a.index};

I put the anchor on B so that no B is missed. The condition need to be placed at A so that the wildcard stops at the correct annotation.

If the As and the Bs share the same offset, you need another, simpler rule with only one rule element and no wildcard..
