A parallelogram with equal sides is always a rhombus,
could be a rectangle, and could also be a square.

A parallelogram with four equal sides is a rhombus.You are a rhombus quadrilateral.
Shapes that do not have equal sides is called a quadrilateral. They include an irregular quadrilateral, rectangle, or a parallelogram.
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.
When it has 4 sides of the same lengths
Parallelogram
An octagon is neither a quadrilateral nor a parallelogram. "Quadrilateral" refers to a shape that has four sides. "Parallelogram" refers to a shape that has two pairs of opposite, congruent sides. An octagon has eight sides, and since eight is not equal to four, an octagon is neither a quadrilateral nor a parallelogram.
