They are quadrilateral shapes whose opposite sides are parallel. In a parallelogram, one pairs of parallel sides may be of a different length to the other pair; in a rhombus all four are the same length.
Since by definition corresponding sides of congruent shapes have the same length, the answer is 1.
No, a parallelogram cannot be a hexagon. A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length, while a hexagon is a polygon with six sides. These are two different shapes with different numbers of sides.
No, octagons just have to be closed shapes with eight sides - the sides do not have to be of equal 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.

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.

A rhombus.
A square has 4 sides that are all the same left.....duhhh!
the same number of sides and internal angles but not the length of the sides.
