Some do, some don't. A parallelogram that has equal sides is usually called either a "rhombus" or a "square". None of the other parallelograms do.

Parallelogram is not a squareAnswerBy definition, all squares are parallelograms because opposing sides of any square are parallel to each other. However, not all parallelograms are square because their sides are not always an equal length, nor are the angles of any two adjacent sides always 90 degrees. Therefore, all squares are parallelograms, but not all parallelograms are squares.
I think they are the same length because they have equal sides and the area would not change.
No. Rhombuses that are also rectangles are called squares. Rhombuses are parallelograms with 4 equal sides, while rectangles are parallelograms where all the angles are right.
A parallelogram has two pairs of opposite sides that are equal in length and parallel. A rectangle has two pairs of opposite sides that are equal in length and are parallel. Thus all rectangles are parallelograms. (A rectangle has the extra condition that all its angles are equal at 90°, thus all parallelograms are not rectangles.) There cannot be a rectangle that is not a parallelogram.
Shapes having less than 4 sides or more than 4 sides are not parallelograms
