A shape with four sides where no side is equal in length is called a trapezoid (or trapezium in some regions). This quadrilateral has at least one pair of parallel sides, while the other two sides can be of different lengths. The sides can vary significantly, leading to a variety of trapezoidal shapes.
A "parallelogram" technically is a shape where opposite sides are equal and any shape with four sides is a "quadrilateral". Every square has four sides of equal length, so a square is both a parallelogram and a quadrilateral. A rhombus(or diamond shape) can have four sides of equal length and can be a parallelogram as well, so either are possibilities.
The rectangle
A square of course!
Its a diamond :]
No shape has four equal sides and four different angles - either there are two pairs of equal angles, or all four angles are the same; or all sides are not the same length.

A Square has four equal length sides
When all sides are equal it has a to be SQUARE. Which is the only shape that is a regular quadrilateral.
A square is a four-sided shape with all sides equal and all angles equal.
It depends on what kind of kite. It could be equal
