"Best" is a subjective criterion when it comes to which units of measurement to use. It would vary from country to countryand depend on why you need to know the area. In general, for a table, square feet or square meters might make the most sense, but I wouldn't rule out square centimeters or square inches. It would be ridiculous to measure the table in square miles or acres.
Metres and centimetres. Or feet and inches. Then square any measurements to find the area.
In metric, you would use square meters and/or square centimeters, depending on how large your table is. In America one might use square inches or square feet.
I believe the answer to this is "area." It is fairly vague and I would need the context of the question to be sure.
You would multiply the length by the width.
There is no direct ratio between square feet and cubic feet as they measure different aspects of an object. Square feet measure the surface area of a two-dimensional space, while cubic feet measure the volume of a three-dimensional space. It would depend on the specific dimensions of the object being measured.

Square centimetres.
Without any units specified, 2 square is a pure number. Furthermore, being a squared measure its units would be square centimetres, not centimetres (which are a measure of length).

Yes, because each of its 4 sides would measure 5 units in length.
inches or centimeters, I would use inches.

Square kilometres for lakes or towns, square metres for rooms or gardens, square centimetres for pictures or sheets of paper are some common units and the magnitudes that they would be used to measure.
"Best" is a subjective criterion when it comes to which units of measurement to use. It would vary from country to countryand depend on why you need to know the area. In general, for a wall, square feet, square yards or square meters might make the most sense, but I wouldn't rule out square centimeters or square inches. It would be ridiculous to measure the wall in square miles or acres.
