You absolutely cannot move attacking units out after the battle, routed or not. It's part of the risk of battle: over committing.The routed units are not fleeing, they are ROUTED. They are completely disorganized, confused, and vulnerable. Retreating units are routed, but routed units are not retreating.
You can move the runes to an empty area. Does it use the word "swap" on the order card? I don't have the game in front of me but I could have sworn that it says "move them freely between two friendly areas" or something to that effect.
Yes, titles start unowned. It's specifically mentioned in the setup rules.
