Any triangle-based pyramid will do. If the sides are all the same length it's then called a tetrahedron.
A pyramid is a generic term for a 3-D polyhedron which has a polygonal base and triangular lateral faces that meet at an apex above the base. If the polygonal base has n sides, the pyramid has n+1 faces, n+1 vertices and 2n edges. A pyramid can, therefore have 4 or more vertices. So, there is bound to be a pyramid that will have the same number of vertices as a triangular prism (6).
yes
A rectangular prism (cuboid) and a hexagon-based pyramid, for example, both have 12 edges. Of the five Platonic solids, an octahedron and a cube each have 12 edges.
That is correct
The given description fits that of a triangular based pyramid which has 4 faces, 6 edges and 4 vertices
there both flat

must all edges of semiregular polyhedron be the same length
A pyramid has 5 faces, 5 corners and 8 edges corners and faces are always the same

the simularites are they have the same vertices and edges
If the number of vertices is not the same as the number of faces, it cannot be a pyramid.

A cube
13 vertices. A pyramid always has the same number of faces and vertices.
No, a square pyramid has a square as a base end the four edges end in the peak. The cube has 8 corners, the square pyramid has 5.
