3D shapes that only have flat faces are known as polyhedra. Examples include cubes, tetrahedrons, and octahedrons. Each of these shapes is composed entirely of flat polygonal faces, edges, and vertices. In contrast, shapes like spheres or cylinders have curved surfaces and do not fit this category.
Cylinders
No, two-dimensional shapes do not have faces in the way three-dimensional objects do. Faces are flat surfaces that make up the boundaries of 3D shapes. In contrast, 2D shapes, such as squares or circles, have only length and width, existing on a single plane without depth.
Only one; a triangle is a 2D shape, not a 3D shape. Usually only 3D (or more) shapes are considered to have 'faces'.
A rectangular prism is the only shape that is made up from only rectangular faces. But there are countless shapes which contain rectangular faces along with other shapes.
There are several of these. For example, dice.See related link below for more shapes

2d shapes are shapes that can only be seen from the front unlike 3d shapes and they are flat
