Any polygon with 4 or more sides can have only two right angles.

regular polygon\
All polygons can have right angles except for circle and ovulated shapes. The only 'regular polygon' that has a right angle is the quadrilateral.
a polygon with 4 right angles and 4 sides of the same length
3 right angles

No REGULAR polygon can have three right angles in it. Any polygon with five or more sides CAN have three right angles, as long as it's not regular.
