No it is not. On a number of counts.
A polygon is an enclosed plane area whose boundaries comprise straight lines. It is, therefore, a 2-dimensional object and so does not have faces. If you meant sides instead, the answer is still NO. If all the sides and and angles are congruent then the polygon MUST be convex.
A regular polygon has equal sides and angles. A polygon has a surface area but a polyhedron has many faces as for example a pyramid.
Any regular polygon has two congruent faces. Many polygons have two or more congruent faces.
A polygon with all sides and all angles equal.

From Wikipedia:A Platonic solid is a convex polyhedron that is regular, in the sense of a regular polygon. Specifically, the faces of a Platonic solid are congruent regular polygons, with the same number of faces meeting at each vertex. Moreover, all its edges are congruent, as are its vertices and angles.
A square is not a solid figure at all. It's a flat figure, with four congruent faces and four congruent angles.
The simplest shape is a hexagonal prism.
A Platonic solid is a convex polyhedron that is regular, in the sense of a regular polygon. Specifically, the faces of a Platonic solid are congruent regular polygons, with the same number of faces meeting at each vertex. They have the unique property that the faces, edges and angles of each solid are all congruent. Some examples are bricks, a dice, tissue boxes and houses.
No. Their "bases" are at right angles to the rectangles connecting the bases.
It is a tetrahedron pyramid that has 4 faces, 6 edges and 4 vertices.
A Cuba has 6 congruent faces
An hexagon is a plain faced 2D polygon that has 6 sides and 6 angles that add up to 720 degrees
