Chris, in regard to your inquiry,
6. Are you thinking of the old Villanova? I believe it was called Wolfetones for a brief time in the early 90's. When you walked in, the bar was to the right and there used to be one of those old shuffle/bowling games against the left wall.
13. The bar you are thinking of on the corner of Queensboro Plaza sounds like the Dublin Bar. A bit of a divey pub, but a good place to get a quick drink or two back in the day.
14. I think the place you are referring to was called the Brazilian Circle, or something similar. It was on 41st Avenue, just north of Queensboro Plaza, and just south of the old LIC HS.
