There is no such thing. A hexagon is a two dimensional figure. A three dimensional figure with six vertices is an octahedron.
The answer is in the question it is a 3 dimensional figure such as a pyramid
It is the cross-section of the figure by the plane.
it's called a face
A pyramid is a four-sided, three-dimensional figure.

It is a three dimensional figure of some sort.

Oh, dude, it's like those flat paper things that you can fold into those cool origami shapes. They're called nets, which sounds way cooler than it actually is. So yeah, you take a net, fold it up like a pro, and bam, you've got yourself a 3D object.

It is simply called a face.
All three dimensional figures have more faces than a one dimensional figure. There are an infinite number of one dimensional points on a three dimensional figure

It is a cube
Pedantically, no. A polyhedron is a three dimensional figure (with some additional qualities). Polyhedra are three dimensional figures.
A two dimensional figure would be an oval or ellipse. A three dimensional shape could be called an ovoid.
