a cube
A skew triangular prism.
take, for an example, a duck. This is a 3d shape because it has three dimensions. Compare this to a square, which is 2d. the difference is that the duck has a beak, and the square does not.
A Triangular Pyramid has 4 triangles and 1 square.
a cube
If you take a regular four sided pyramid and chop off the top, parallel with the base, the left over piece would be a solid with four identical trapezoidal faces and a square top and bottom. The only name I know is 3-D trapezoid.

A 3d shape with 5 faces can be a square pyramid
The simplest such shape is PYRAMID.
A 3D shape with nine faces is called a "nonagon prism." In this geometry, the two bases are nonagons (nine-sided polygons), and there are additional rectangular faces connecting the corresponding sides of the two bases. This results in a total of nine faces: two nonagonal faces and seven rectangular lateral faces.
