A decagonal based pyramid will have 11 faces, 11 vertices and 20 edges
11 vertices (one more than the number of vertices in the base).
It depends on a decagonal what. A decagonal prism has 20 vertices. A decagonal pyramid has 11 vertices.

Not a polyhedral shape. You need at least three vertices to define a plane shape. With 5 vertices, the maximum number of triplets you can get is 10 so there cannot be 11 faces.

A heptahedron has 7 faces. It can have 6 vertices and 11 edges, or7 vertices and 12 edges, or8 vertices and 13 edges, or9 vertices and 14 edges, or10 vertices and 15 edges.
