cube rectangular prism anything with 8 vertices on the 3d plane
ones that can be drawn in the plane such as a triangle, circle, etc. A sphere is not one.
The following are some examples of a shape with two flat face and one curved surface: A sphere intersected by two planes. An ellipsoid intersected by two plane faces. A paraboloid intersected by two plane faces. A cone intersected by two plane faces. A cylinder. A hyperboloid intersected by two plane faces.
plane figures.
A plane is a two dimensional figure that is a set of line segments or sides all lying inside of a single plane. Some examples of plane figures are a triangle, pentagon, octagon, hexagon and circle.

Rectangle
If restricted to plane faces, a rectangular pyramid or a triangular prism. With curved faces such shapes will usually not have names.
3 rectangles, 2 isosceles triangles
Any plane shape on the side of a polyhedron is called a face.
A triangle (and all 2-dimensional or plane figures) have only one face.

2 dimensional (plane) figures can have three or more straight edges as sides. 3 dimensional (solid) figures can have four or more plane sides (faces). They can have fewer sides if the sides are not straight.
An irregular polyhedron if it has plane faces. If not, then there usually will not be a name for it.
