There are no 90 degree angles in a cone. This capital 'L' shows an example of a right angle.
A cone does not have right angles.
A cone has no acute angles because a cone is a 3D shape and not a 2D.
A two dimensional regular pentagon does not contain any right angles. A pentagonal prism, however, contains up to 10 right angles.
Many shapes have a right angles. For example, a right angled triangle, square or rectangle all contain at least one right angle. Trapeziums may also contain right angles. Any irregular polygon may also contain a right angle.

No right triangle can have any obtuse angles inside it.
Just one.

None because it can only have 1 right angle and 2 acute angles to be a right angle triangle and the 3 angles add up to 180 degrees.
4 right angles, no other angles.
