I have been seeing a few bees fighting at the entrance to one of my hives, not what I would have expected if I was getting robbed, but fighting none the less. Also seemed like more activity than usual, but this is my strongest hive. I am new, so I was hesitant to try a robber screen, I didn't want to block their progress for a couple days if they didn't need it, but went ahead and put one on. Here is the pic from this morning. Looks like a bunch of free loaders waiting for the door to open.
So, 2 questions---Is 2 days long enough to leave the screen on? and should I screen my other hive (right next to this one) just in case?

I'm not familiar with the robber screen you are using, but I don't see an entrance on top for the house bees. A robber screen should allow the house bees to enter at the top while the robbers are trying to get in at the bottom. If set up properly, a robber screen can be left on indefinitely.

You want one kinda like this.

The side you see goes against the box.

This one is for a Nuc.

I made this one myself. Here is a pic from this afternoon, the red arrow shows the top opening. Is it big enough? It is about a half inch wide. How long till they give up?

Mine are open all the way across the top. It looks to me like the house bees are trying to find their way home.

The robbers will stay at the bottom they are following the smell of the honey issuing from the bottom opening.

Look at the pic. of mine above, the top is open all the way across, the bottom notch is the same size opening as the nuc has.

After several days the robbers generally give up.

Iddee, they find that little opening just fine. Especially if you put the screens on at night while they're all inside. They orient to the new exit the next morning. There is, however, sometimes a pileup when the foragers all return at the same time!
