Ok, at first glance, everything looks OK. Have you put them in the correct factions? The code for the playertemplates ini should be in the "PlayerTemplate FactionMen" block and the code for the skirmishaidate ini should be in the "ArmyDefinition MenOfTheWestArmy" code block.
I'm guessing that the "_SEE" at the end of most of the hero's names is meant to be there, like that is in fact part of the hero's actual name in the hero's own file in it's unit folder?
Also, there are 10 heroes there, that is way too many to get in the radial commandset of the fortress. You will need make at least 4 heroes before the rest start showing.
Did that. Checked that.
Here's an idea, what if I put them before the Rohan heroes (since a rohan base is needed for them). Let's see...
nope
