I can't seem to get any extra ladders to work. I've tried keeping them named as pasted - with the "(#)" at the end and tried renaming them to just the "Ladders". I also tried putting all under just one "Ladders".
I need 5 ladders for the map I'm making {2 of them are double height}. How do I do this?
You need to duplicate the "Ladder" object that is located inside "Ladders", to do it, simply select "Ladder" then Ctrl + D to create a copy

Basically the "Ladder" is a simple object with a BoxCollider component which represents the climb area, so to make a bigger ladder you need to resize the height of the collider. After that, expand the "Ladder" object and duplicate the "MetalLadder" (what you see as a metal ladder in game), then move it up to match the dimensions of the collider.
