yes

No. The glass measures to the nearest quarter of an inch, which means the measurements could be as much as 1/8 inch too big or two small in each directions.

No. Without a zero tolerance for larger dimensions, it could be larger than the opening. A clearance (smaller size) with a zero tolerance above 7 1/8 by 9 3/8 should have been specified.
Hardware stores should be able to provide +/ 1/8" tolerance (maximum error) on cut glass.
