Any regular polygon with more than 4 sides has angles of more than 90 degrees. Some examples would be:

Yes, there is a maximum number. Recall that the sum of the exterior angles is 360 degrees regardless of what kind of polygon it is. Since an obtuse angle is and angle that is greater than 90 degrees, four of them would be greater than 360 degrees so we could not have that in a polygon. Therefore, the maximum number of obtuse angles is 3.
An angle that measures more than 90 degrees but less than 180 degrees is called an "obtuse" angle. Note Angles less than 90 degrees are called "acute" angles. An angle that is exactly 90 degrees is called a "right" angle. Angles that are more than 90 degrees but less than 180 degrees are call "obtuse" angles. An angle that is exactly 180 degrees is called a "straight line". Angles that are more than 180 degrees and less than 360 degrees are called "reflex" angles.
An angle measuring 193 degrees is considered a reflex angle. Reflex angles are angles that measure greater than 180 degrees but less than 360 degrees. They are typically seen in shapes with more than 180 degrees, such as a concave polygon. In this case, the angle of 193 degrees falls within the range of a reflex angle.
octagon, trapezoid, pentagon...* * * * *Not true.A trapezium (or trapeziod) must have at least one acute angle.Any regular polygon with 5 or more sides has all obtuse angles. However, an irregular polygon can always have one or more non-obtuse angles (acute, right or even reflex).
The three angles are 40, 50 and 90 degrees.
