Four-sided polygon.
you mean a quadrilateral and,a square...
Lateral means side, quadrilateral (4 sides)
If you mean a quadrilateral shape then it is any shape that has 4 sides.
If you mean can a circle always be drawn round a quadrilateral so that the quadrilateral is enclosed within the circle then yes as long as the diameter of the circle is large enough. If you mean can a circle always be drawn around a quadrilateral so that it passes through all vertices then only if the opposite angles of the quadrilateral add up to 180o - such quadrilaterals are called cyclic quadrilaterals.
A regular polygon has all sides equal in lengths. A quadrilateral is a 4 sided polygon.
If you mean "square", yes.

If it is a quadrilateral it cannot be "not a quadrilateral"!
If you mean a parallelogram then it is a 4 sided quadrilateral with opposite parallel sides

do you mean a 'rectangle'? or a 'parallelogram'? or a 'quadrilateral'?

You don't. There is no such thing as the "sum of a quadrilateral". If you mean the perimeter, you add the lengths of the four sides. If you want the area, you can divide the quadrilateral into two triangles, or some other shapes, calculate the individual pieces, and add everything up.
