A rectangular prism is not considered a regular polyhedron because its faces are rectangles, which can vary in size and shape. A regular polyhedron, or Platonic solid, has congruent faces that are all the same shape and size. In the case of a rectangular prism, while it has six faces and is a three-dimensional shape, the faces can be different dimensions, making it irregular.
Since you use the term "faces" of a shape, you may be referring to polyhedra,which are three dimensional solids. There is no maximum number of faces a polyhedron can have. But for regular polyhedra (a special case where all faces are congruent regular polygons), the regular polyhedron with the most faces is the icosahedron, which has 20 faces, each of them an equilateral triangle. The most familiar regular polyhedron is the cube which has six square faces.
Six faces.
A solid that has faces that are the same size and shape is called a regular polyhedron. The faces of a regular polyhedron are all congruent, meaning they are identical in shape and size. For example, a cube has six square faces, all of which are the same size and shape. The term for each individual face is simply referred to as a "face."

Six faces.
The solid shape/figure that has six rectangles as faces is called a rectangular prism. The general term for any shape with six faces, regardless of shape is a hexahedron.
