I agree with @PolyGeo, this type of processing tends to be much easier if scripted in python, as you are now discovering the limitations of modelbuilder, not particularly great for looping type workflows. That said if you have the very latest version of ArcPro (2.7) then you can use the new Iterate Layers iterator which can step through layers in a map ...

I find ModelBuilder not suitable for this type of processing and is done much easier with a Python script. That said and as you appear to be seeking a ModelBuilder solution, you say you have a 1 to 1 numeric match between table and featureclass. Explore using a single model driven by a FOR iterator this will create your 1,2,3... and using inline variable ...

If something is a parameter, the default geoprocessing environment is set to add those outputs to your map. Note - you cannot add the result to an MXD other than the one you're in. To do that, you'll need to write a Python script, make that into a tool ...
