Yes, there is a limit, 1 for a triangle, 4 for a quadrilateral, 3 for a pentagon, 5 for an hexagon and for a heptagon, 6 for an octagon, etc. Should be a formula for this.

The maximum number of right angles in a polygon is determined by the formula (n-2), where n represents the number of sides in the polygon. A polygon with n sides can have a maximum of (n-3) right angles, as the sum of interior angles in a polygon is given by (n-2) * 180 degrees. Since a right angle measures 90 degrees, the maximum number of right angles in a polygon is limited by the total number of interior angles.
All polygons can have right angles except for circle and ovulated shapes. The only 'regular polygon' that has a right angle is the quadrilateral.
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.
Interior angles of n-sided polygon total (2n - 4) right angles or 180n - 360 degrees.
