A right angle is an angle of 90 degrees. Any angle not 90 degrees is not a right angle. End of story.
Any polygon can have a right angle. A right angled triangle is an example.
A Triangle which do not have a right angle.
Any polygon can have one right angle, for example, a right angled triangle.
Any polygon, if it is not regular, can have 1 right angle.

An angle in a hexagon can have any value at all. It can be acute, a right angle, an obtuse angle or even a reflex 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.
It can be any length; a right angle triangle just needs to include a right angle somewhere. But length has nothing to do with whether it is a right angle or not.
No that is a right angle. An obtuse angle is any angle over 90 degrees.
No. A right angle looks like a corner and is 90 degrees.
That would be a right triangle. Any triangle that has a right angle in it is a right triangle.
