If you can keep her in sight of her friends that's great, but I would bring her inside just for the night to keep an eye on her. It sounds like she just has a minor injury and she might be fine in the morning. It's just a good idea to keep an eye on her for a while.
The right foot looks like there's a bit of a sore on there. I would try a warm (quail body temp or a tiny bit warmer) epsom salt bath and see if you can get another picture of the bottom of the foot.
I can't tell for certain, but it looks like the right joint is a bit swollen too. Keep her...
