Complimentary angles
Any two angles who's measures add up to 180 degrees form a straight angle.
The sum of two complementary angles is 90 degrees. The three angles of a triangle add up to 180 degrees. Hence, if you subtract the complementary angles from 180, you have the measure of the third angle: 180 - 90 = 90 (this is the third angle) As a rule, if two angles of a triangle are complementary, the third angle is a right angle (90 deg). The three angles together form a right triangle.
The complementary angles form a right angle with the shared ray.
Not possible... The internal angles of a quadrilateral always total 360. If you MUST have an angle of 90 degrees - the remaining angles must total 270. At least one of the remaining angles will always be obtuse.
Right angles aren't formed by other angles - it is already an angle itself. However, if you bisect a right angle, it becomes two acute angles.
2 right angles will form a supplementary angle of 180 degrees
By a straight angle I assume you mean an 180° angle, so two angles that form a 180° angle would be called supplementary angles.
Two angles are called suplementary angles if they form a straight angle, that is to say 180 degrees.

Intersecting two perpendicular lines will form right angles.
They do if they are added ... placed together so that their vertexes and one side of each angle coincide. That's the definition of complementary angles.
