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
Triangular based pyramid with no bottom. That is, if you meant 3-D shapes, presumably?
cube 8
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.
A 2-d shape is a two dimensional shape meaning it is flat.
