You call it a parallelogram.
It is a regular quadrilateral in the form of a square
quadrilateral quadrangle
A shape with five sides would be a pentagon, but a shape can not have 5 right angles. Squares and Rectangles are both shapes with 4 sides and 4 right angles. They are the only shape with the same amount of right angles as there is sides.
Perpendicular side meet at right angles.

It is a regular quadrilateral in the form of a square
quadrilateral quadrangle
If three of the angles of a quadrilateral are right angles, then the fourth angle must also be a right angle. The sum of the interior angles of any two-dimensional (planar) geometric figure must add up to 360 degrees. As this is the case, three times 90 equals 270, and 270 subtracted from 360 leaves 90. The quadrilateral described here is a rectangle. If all the sides are the same length, it is a special case of a rectangle that we call a square.

i think you call it a irregular quadrilateral
The minimum number of sides for a polygon is 3 sides.

A rectangle is a quadrilateral with 4 right angles (90 degrees) and two sets of parallel lines. The definition of a rectangle includes the the shape of a square, but a square has an added rule, that all sides must be equal. So a square is a rectangle. Oblong is a term for non-square rectangles.
