square
Shapes with 4 sides are called quadrilaterals. If all the sides of the shape have the same length, then there are two options for specific quadrilaterals. These are squares or rhombuses. If the pairs of sides are not the same length as each other, then there are two alternate options for the shape. These are rectangles and parallelograms.
There are infinitely many such shapes. A polygon with 4 or more sides can have two sides that are parallel and they need not be the same length.
A rectangle has 4 sides not the same length and 4 right angles.
Rectangle, parallelogram
square
A square will have 4 sides that are all the same length, and 4 angles that are 90 degrees each. Other shapes will have 4 sides, but they may be of different lengths. Other shapes will have 4 equal sides, but not 4 angles of 90 degrees.
Trapezoids and rhombuses are quadrilateral shapes. A trapezoid has 2 sides that are parallel and a rhombus has 4 sides that equal the same length.
If you mean 'Irregular' and 'Regular shapes' then this is the answer. A regular shape is a shape that has E.g. 4 sides that are the same length but and irregular shape is one that has the same amount of sides, just different lengths.

they are a shape with 4 sides and the sides are not the same lenth
I don't know if there's a specific name for these two shapes, but the only two shapes that have 4 equal sides are the square and rhombus. The difference between the two is the square has 4 equal angles (90 degrees) and a rhombus does not.
They can be, but they do not have to be. A rectangle has 4 sides and 4 right angles. Which means a square, which is a type of rectangle, would have 4 of the same length sides.

The 4 sides of a square are equal in length
