There are no triangular prisms in faces. Faces are 2-d shapes and these cannot contain 3-d shapes in them.

No, they have only one face.
a cube has parallel faces so does a cuboid and so does a cylinder and also if you want to find out lots more stuff about 3-D shapes or 2-D shapes see the website in the related link
no. a 2d square has only 1 face but a 3d square (cube) has 6 faces.
a net is what you get when you unfold a geometric shape into a 2-d flat surface
Two-dimensional shapes, or 2-D shapes, are flat figures that have two dimensions: length and width. They do not have depth or volume. Common examples include squares, circles, triangles, and rectangles. These shapes can be defined by their properties, such as the number of sides, angles, and symmetry.
Triangular based pyramid with no bottom. That is, if you meant 3-D shapes, presumably?

3-d shapes are not made from 2-d shapes. 3-d shapes may have projections onto a plane that are 2-d.
No. A sphere is a three dimensional shape which has no polygonal faces. Similarly an ellipsoid, a torus, a paraboloid, hyperboloid etc are 3-D shapes with no polygonal faces.
