Do all amazon sward plants shoot out "runner stems"? Or is this a weird male/female plant type thing? Will it shoot out runner plants if it essentially is a runner plant?
Yes, swords shoot out runners. It's a form of asexual reproduction. I'm not sure what the second half of your question is asking.
Once the grow large enough, yes, they will.
I've seen six inch tall amazons with runners. Mine didn't shoot a runner until it was almost ten. It's variable.
