The figure described is a polyhedron. It is a tetrahedron known as a triangular pyramid.
It is called a face of the polyhedron.
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.

In geometry a pyramid is a generic term describing a shape that consists of a base that is a n-sided polygon, and n triangular faces attached to each of the polygon's sides which meet at an apex above the base. A pyramid with an n-sided polygon as base has n+1 faces, n+1 vertices and 2n edges.
A triangular pyramid is a pyramid that has 4 faces where each face is a triangle. Just type it in on www.google.com/images
All the faces of a pyramid MUST be polygons.

A solid with a regular polygon for each face is known as a perfect solid.

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.

I presume the question is meant to be: How many sides does a pyramid have? The answer is 4 or more. A pyramid has a polygonal base where the polygon can have 3 or more sides. Corresponding to each of these sides there will be a triangle rising to the apex of the pyramid. In all, a pyramid whose base is a polygon with n sides will have n+1 faces (sides).
