Is there a way to combine all queries into one for output from a flow?

This is your page flow??

Anyway I can’t understand…

Let’s go with what you say.

Is any of your queries a single record one? (not multiple?)

I found this and maybe is related…

Join data transformation doesn't work with single query

It maybe is not documented that good, but all the data transformations only work on collections/arrays. A workaround would be to just not use single query but use the mutliple records and limit that to 1.
