If its a triangle then just the one but if it is a square or a rectangle then 4 of them.

one

A triangle can only have a maximum of 1 right angle. The total degrees of all the angles of a triangle adds up to exactly 180. Since a triangle must have exactly three angles, it is not possible for the triangle to have more than one angle that is 90 degrees.

Just the one and the other two angles must then be acute angles

There is no such shape since an angle can always be added to any shape.

A triangle can have up to all three acute angles. An equilateral triangle has three- sixty degree angles, which are acute.

Two of them and they must add up to 90 degrees

A right triangle cannot contain any obtuse angles. The right angle represents 90° and the total of all three angles must be 180°. There is only 90° left for the remaining two angles, so neither can be obtuse (greater than 90°).

0. A right triangle, by definition, will never include any obtuse angles.
