The place where two faces (planes) intersect is called an edge.
It is a vertex.
the place where two faces intersect
Where two faces meet on a 3D figure is called an edge. An edge is the line segment that connects two vertices, which are the points where the faces intersect. In polyhedra, edges play a crucial role in defining the shape and structure of the figure. Each edge is shared between two adjoining faces, contributing to the overall geometry of the solid.
Two lines cross or intersect at a point.
No. The faces of a tetrahedron are equilateral triangles, but none of the faces is parallel to another one of the faces -- they could not be parallel, since by the definition of a tetrahedron, all the faces intersect(!) and parallel planes do not intersect.

That would be classified as an edge.

A pyramid never has parallel faces. Any two faces intersect.

I believe it's called a vertex
