4, making it a rectangle or a square. If you don't want either of those, then 2.
Can't have 3 because interior angles total 360o.

A quadrilateral can have four right angles.
An irregular four-sided shape, or quadrilateral, can have anywhere from zero to four right angles. The specific number of right angles depends on the individual angles of the shape; for example, a rectangle has four right angles, while a trapezoid may have none. Thus, the count of right angles in an irregular quadrilateral can vary widely.

No because a quadrilateral has 4 sides but doesn't have to have right angles. For example the. Trapezoid doesn't,t have right angles but it is a quadrilateral
All quadrilateral have four angles. It is possible that all four angles are right angles, even if the quadrilateral is not a square (this would be a rectangle).
A Rectangle or a square. The word 'rectangle' comes from Latin and means 'Right(Recto) Angles'.
Can be a Parallelogram, a Rhombus, A Kite, or a Trapezium. However, A kite may display one right angle, depending on its angular measure. An Asymmetric Trapezium may also display two adjacent right angles. A Symmetric Trapezium does NOT have any right angles. NB A Square has four right angles. A RECTANGLE has four right angles. The word 'Rectangle' is from its Latin base , meaning 'Right(rect) Angles).
If it is a quadrilateral it cannot be "not a quadrilateral"!
A quadrilateral having four right angles is called a rectangle.
A **Quad**rilateral is any 2-dimensional figure of four sides. Not all quadrilaterals have right angles. Right-angled quadrilaterals are squares and rectangles. None right-angles quadrilaterals are parallelograms, rhombus, trapezium, and kite.
A quadrilateral is any shape with four sides; angles can be acute or obtuse. A perfect square is the only quadrilateral with only right angles.
A quadrilateral can have four right angles.

It's impossible for a quadrilateral to have no equal sides and have right angles.
An irregular four-sided shape, or quadrilateral, can have anywhere from zero to four right angles. The specific number of right angles depends on the individual angles of the shape; for example, a rectangle has four right angles, while a trapezoid may have none. Thus, the count of right angles in an irregular quadrilateral can vary widely.
The sum of the interior angles of a quadrilateral is 360 degrees. If three of the angles are right angles, that is, of 90 degrees each, the the fourth must be 90 degrees. So you can have a quadrilateral with three right angles but its fourth angle will also be a right angle. So exactly 3 right angles is not possible.
