All the faces of a pyramid MUST be polygons.
A triangle if it is a triangular based pyramid
A pyramid has triangular faces that converge at a single point called the apex. The base of the pyramid can be any polygon, and the number of triangular faces corresponds to the number of sides on the base. For example, a square pyramid has four triangular faces and a square base.
a pyramid
No, a rectangular pyramid is not a polygon. A polygon is a two-dimensional shape with straight sides, while a rectangular pyramid is a three-dimensional shape with a rectangular base and triangular faces that converge at a single point (the apex). Thus, while it has a polygonal base, the pyramid itself is classified as a polyhedron.
A pyramid has a single polygonal face as its base.

24 faces including the base face
A polygon is a many sided 2-dimensional figure, and thus could never be "solid" Alternatively, it could be "one face that is a polygon". In that case the solid could be like a pyramid that morphs into a cone or a part-sphere. The base would be the one polygon, the other face would not.
A cylinder is a polygon that has circles as its base. A triangular pyramid is a polygon that has a triangle as its base.
A pyramid can have 4 or more faces. A pyramid, with a n-sided polygon as base will have n+1 faces. The polygon with the least number of sides is a triangle and a triangular pyramid (tetrahedron) has 4 faces. A square based pyramid has 5 faces, and so on.
Depends on the pyramid. A pyramid with a square (or quadrilateral) base would indeed have 8 edges, but a pyramid can have any other polygon as a base.Depends on the pyramid.

The figure described is a polyhedron. It is a tetrahedron known as a triangular pyramid.
