Are there places to sit like benches or chairs

There are, but finding one in the shade that is the question

Yes

Some

Yes, but only one person to a bench

Yes with short distances apart as far as walking goes.

Yes. They are spread around the outlet area.

I agree, there are benches along the paths between the stores where Soma, Off 5th Ave, J Crew, etc are located. There are a couple of round fountains where you can sit on the edge of those fountains. I don't recall if there are benches along the strip that has TJ Max, Whole Foods, Old Navy etc.
