It depends whether its regular or irregular.
A regular 8 sided octagon has no acute angles but has 8 equal obtuse angle of 135 degrees that add up to 1080 degrees
8 if it's an regular octagon
An regular 8 sided octagon has no right angles unless it is shaped into an irregular octagon.
A regular octagon has 8 interior obtuse angles.
8 angles
It depends whether its regular or irregular.
it has no acute angles
A regular 8 sided octagon has no acute angles but has 8 equal obtuse angle of 135 degrees that add up to 1080 degrees
In a regular octagon, each angle is 135 degrees. If the octagon is not regular, then it can have as many as 6 right angles in it.
Whether it is a regular or irregular octagon does not matter. An octagon is, by definition, a 2-dimensional figure with eight sides, and therefore with eight angles. A regular octagon will have eight equal angles and an irregular octagon will have eight angles some of which are not equal to the others.

8
A regular octagon has 8 interior obtuse angles.
None.
Whether or not a polygon is regular makes no difference to the number of sides or angles that it contains. An octagon has eight sides and eight angles.
