A shape with four sides that are not equal is called a trapezoid (or trapezium in some regions). In a trapezoid, at least one pair of opposite sides is parallel, while the other two sides can vary in length. This results in a four-sided figure with unequal side lengths. Other examples of quadrilaterals with unequal sides include irregular quadrilaterals.
A parallelogram is a four sided shape where opposite sides are parallel and equal lengths. If you mean that ALL sides are equal lengths, you are looking for a rhombus.
A rhombus is a shape having two acute angles and four equal sides.
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.
A square is a two-dimensional shape with four equal sides and four right angles.

A rectangle has four sides with two equal lengths.

The rectangle
The shape with equal sides next to each other is a square. A square has four equal sides and four right angles, making it a specific type of rectangle. Another shape with equal sides next to each other is an equilateral triangle, which has three equal sides and angles.
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 shape with four equal straight sides is a square. In addition to having equal sides, a square also has four right angles. Another example of a shape with four equal sides is a rhombus, although its angles are not necessarily right angles. Both shapes are classified as quadrilaterals.
There is no such shape. If the four sides are equal it MUST be a parallelogram.
