a vertex
A vertex is the name of a corner on a solid where three or more faces meet (plural = vertices).
The solid where two faces meet is called a "polyhedron." A polyhedron is a three-dimensional shape that consists of flat polygonal faces, straight edges, and vertices. Each point where two faces come together is called an edge, and the points where edges meet are called vertices. Examples of polyhedra include cubes, pyramids, and tetrahedra.
an edge
The corner of a solid where two faces meet is called a "vertex." In three-dimensional geometry, a vertex is a point where edges converge, and it is one of the key elements in defining the shape of a solid. For example, a cube has eight vertices.

an edge or in more simpler term "side"
If the faces are flat, it's a line.

The edge.
There is no specific name for lines that meet at one point, but lines that meet at a point, the point is called the intersection point.
vertex
Where faces meet there are edges and where edges meet there are verticies
