A star has 10 sides and 5 vertices but if it's a decagonal star then 20 sides (10 for the star and 10 for the star) and 10 vertices (for the decagon in the middle, hence decagonal star). But, if it's pentagram star then 10 sides and 10 vertices.

An octagon has eight sides and eight vertices. An octagon has 8 sides and 8 vertices.
Yes, they can have sides and vertices.

A pentagonal pyramid (5 sides and 1 base) has 6 faces, 6 vertices, and 10 edges (5 between the sides and 5 with the base).

An octagon has eight sides and eight vertices. An octagon has 8 sides and 8 vertices.
6 sides and vertices
Yes, they can have sides and vertices.
A triangle has three sides and three vertices.
3 sides and vertices, 5 sides and vertices, 7 sides and vertices, and so on. There is no other pattern, necessarily.
