polyhedron
A 14-faced 3D shape is called a tetradecagon if it refers to its polygonal faces. If it is a polyhedron with 14 faces, it could be a type of polyhedron like a truncated tetrahedron or another complex shape, but there isn't a specific common name for a polyhedron with exactly 14 faces. The classification depends on the nature and types of the faces involved.
A 'hedron' from Latin. Hence 'polyhedron' a many sided three dimensional object.
An irregular polyhedron if it has plane faces. If not, then there usually will not be a name for it.
a polyhedron * * * * * That is only if it is bounded by plane faces. A sphere, for example, is a three dimensional shape but is not a polyhedron: it is a solid shape.
Any polyhedron.
An icosahedron is a polyhedron has 20 faces, and is a 3D shape.

None. A polyhedron is 3 dimensional and you cannot make a 2 dimensional shape out of 3D shapes.
Any polyhedron.
An eight-faced 3D shape is called an octahedron. Any 3D shape (polyhedron) ends in -hedron, just like any 2D shape (polygon) ends in -gon, and octa- means 8.
It cannot be a polyhedron nor any "normal" 3d shape.

The faces in a 3-D shape (polyhedron, for example) are bordered by edges.
An irregular polyhedron if it has plane faces. If not, then there usually will not be a name for it.
