hexagon and octagon.
A shape with five sides would be a pentagon, but a shape can not have 5 right angles. Squares and Rectangles are both shapes with 4 sides and 4 right angles. They are the only shape with the same amount of right angles as there is sides.
A straight line
This shape has only one pair of opposite sides and no right angles: <
If there are no angles, all you have is a 'straight side'. There is a plane and no shape. Maybe you are thinking that straight means standing up straight. You might then be thinking of an upright tube.

A shape with five sides would be a pentagon, but a shape can not have 5 right angles. Squares and Rectangles are both shapes with 4 sides and 4 right angles. They are the only shape with the same amount of right angles as there is sides.
A shape with parallel sides but no right angles is called a parallelogram
