An octagon is a 2 dimensional object, not a 3 dimensional object. As such, it has 1 face, 8 corners, and 8 angles.
A heptagon.
A Pentagon
Rhombus
In a real star, no. In a 2-dimensional star-shape, no. In 3-dimensional star-shapes, yes, there can be.

uhh, a triangle?
No, they are two-dimensional.
In a real star, no. In a 2-dimensional star-shape, no. In 3-dimensional star-shapes, yes, there can be.
A square.
A cube is not something that can be grown, but instead a 3-Dimensional object that has equal angles equal lines on a 2-Dimensional Scale, and 6 total surfaces, and 24 angles, all of them right.
A trapezium prism has 8 vertices. Each of these is made up of one solid angle. So, in terms of solid angles the answer is 8. However, each vertex is also a point where 3 planes meet and, between them, these form three 2-dimensional angles. So there are 24 2-dimensional angles in all.
A regular pentagon.
