Yes
Yes. Having been here a few times and double checking in the app, it looks like they only have one or two auditoriums thats have reserved seating. I have never seen a sold out auditorium because they offer so many seats for each movie though, so its highly unlikely the movie and time you want to see it will be sold out.
If the show is not full, yes.
Yes you can purchase tickets at the ticket window just prior to the start of the movie.
