comment Directed multigraph with numbered edges
@Casteels: Accordingly my understanding "edge-labeled directed multigraph" may have labels which are not natural numbers, have duplicate labels for two different edges starting in the same vertex, etc. So, I think this is not an answer

It seems that there is a simple solution: Just restrict for the case when $a$ are trivial ultrafilters. No I am checking that this is a correct solution.

comment Filters on a set of filters, are they equivalent to just filters?
@PatrickDaSilva $U$ is a set. It does not "have poset structure".

comment A term for category where every loop of morphisms is an identity
An additional property of my particular category, is that there exist isomorphisms between every two objects. Is there a term for this?
