A parallelogram requires that opposite sides are parallel and of the same length; it is not a requirement that all four sides are of the same length. A rhombus requires that opposite sides are parallel and all four sides are of the same length. It is possible that a parallelogram can have all four sides of the same length; when it does it now fulfils the requirements of a rhombus, and so is a rhombus. Thus a rhombus is a type of parallelogram (all rhombuses are parallelograms), but there are parallelograms which are not rhombuses (those where there are two sides of one length (opposite and parallel) and the other two sides of a different length).
A Rhombus
This would be a parallelogram or a rhombus. A parallelogram is like a pushed over rectangle and a rhombus a pushed over square. All sides are equal length and parallel on a rhombus but opposite sides are equal and parallel on a parallelogram. None of the sides are joined by 90 degree angles.
Rectangle, parallelogram
If a parallelogram has all four sides the same length it's called a square.
No.

That would be a parallelogram, right.
No. But the opposite sides do - in pairs.
A square.

All four sides of a rhombus are the same length. In a parallelogram there are two pairs of sides with equal lengths but one pair is different from the other pair.
Rectangle, parallelogram
In a rhombus each of the sides is of the same length whereas in a parallelogram, each pair of opposite sides is of the same length but the two pairs are different.
