But question: What do you need to round it to?

For banquets, a 6 ft (72inch) round table is typically used to seat 10 people comfortably
No it will not fit. It will sit on the table like a large, odd-looking place mat. Tablecloth measurements refer to the exact size of the table cloth, not to the size of table it will fit. For a 96 inch diameter round table, you'll likely need a 120 inch diameter tablecloth to allow for 12 inch overhang all the way around. You can use a 108 inch round, which will give you a 6 inch drop or 120 inch round, which will give you a 12 inch drop or 128 inch round, which will give you a 16 inch drop
Table linen size will depend on the drop you need. For a 5 foot diameter (60 inch) ROUND table and using a 90 inch ROUND tablecloth your drop would be 15 inches all around the table. For a 5 foot diameter (60 inch) SQUARE table and using a 85 inch SQUARE tablecloth your drop would be 12 and a half inches all around.
You need at least 4 yards of fabric to make a 70 inch round table cloth. Most people would use close to 6 yards to make the designs that they'd like to.
You need to calculate the diameter of the table, then find the square of that. So, assuming the circumference is 48, the diameter is 15.27889. 15.278892 = 233.4444. You'd need approximately 233.45 square inches.
Assuming you are talking about a 60" diameter table and a regular octagon (regular being of equal sides) you would need a room that is 60" across. If you wanted chairs, add 30".
Depends on the height of the table !
That completely depends on the height of table top above the floor. The width of the tablecloth needs to be the width of the table (60") plus twice the height from the floor. So, if the height from the floor is 30", the tablecloth needs to be 120" wide.
To figure this out, you'll need to know that the circumference of a 40" table is approximately 126". Many designers allow about 30" of space per person at the table's edge, especially in commercial applications. Therefore, 4 people can fit at a 40" round table. (For residential settings, you can sometimes plan for 24" per person and might be able to squeeze in an extra chair.)

For a 60 inch table, you would typically need a tablecloth that is at least 90 inches to allow for a 15-inch drop on each side. This will provide a nice overhang and coverage for the table.
