A right angle, by definition, is 90 degrees.
If you mean what are the other angles in a right triangle, you need one of the other angles in the triangle or the length of one side (not the hypotenuse) any two sides. You can then find the third side by Pythagoras, then the other two angles by simple trigonometry.
Yes. A right triangle is a triangle where one angle is a right angle. If two out of three angles are right angles, then it's an isosceles triangle. If all three angles are right angles, then it is an equilateral triangle.
Does. a 90° angle have right angles
right angle triangles have right angles, but there is no such thing as a right angle kite
A square has 4 right-angles. A right-angle triangle has 1 right-angle
A right-triangle has a right angle (90o) and two acute angles.

A Triangle which do not have a right angle.
right angles
A right angle only has one angle.
It can have a right angle, or more than one right angle, but it also is possible that it does not have any right angles.
Yes. If it has ONE right angle, then ALL four angles are right angles.
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.
A right angle has one angle, notice the words, "A right angle" (emphasis on the "A"), if it were a right triangle it would have 3 angles (TRIangle, tri means three).
