NO
A hexagon is a six sided figure so, a hexagonal base has six triangular sides. Each triangle has three vertices, so such a pyramid has 18 vertices
Subtract 1 from the number of vertices. Find the name of the polygon with that many sides. The pyramid has that polygon as its base. So, for example, 7 vertices. Subtract one and that gives 6. A six sided polygon is a hexagon. So the shape is a hexagon based (or hexagonal) pyramid.
It has 12 vertices
The number of vertices does not determine the number of faces. If the shape with 6 vertices was a quadrilateral based bipyramid, it would have 8 faces. A hexagonal based pyramid has 7 vertices and 7 faces. So more vertices does not necessarily imply more faces.
yes
Add one to a hexagons number of vertices

To find the number of vertices on any pyramid, take the number of corners on the base and add 1 (for the top) A hexagonal based pyramid has 7 vertices (6 for the hexagon, 1 for the top) I suspect you might mean "hexagonal prism" though. In which case, for prisms, you double the number of corners in the 2D shape. A hexagonal prism has 12 vertices (6 for the hexagons at each end.)

No. A pyramid can have any number of vertices from 4 upwards.
No. A triangular prism has six vertices. A square pyramid has five vertices. A triangular pyramid has four vertices.
yes
Two times the number of vertices in the polygonal base of the pyramid.
If the number of vertices is not the same as the number of faces, it cannot be a pyramid.
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges. 6 sides, 1 base = 7 faces Save
