A rectangular prism has 6 vertices (or corners) and a rectangular base.

A three-dimensional figure with five faces, nine edges, and six vertices is called a triangular prism. It consists of two triangular bases and three rectangular lateral faces. The triangular bases contribute three edges each, and the three additional edges connect the vertices of the triangles, resulting in the total of nine edges. The six vertices come from the three vertices of each triangular base.

There is no such thing. A hexagon is a two dimensional figure. A three dimensional figure with six vertices is an octahedron.
a cube

There is not such thing as a three-dimensional triangle. You are thinking of a tetrahedron which is a three-dimensional figure with each side being a triangle. This has four vertices.

The easiest way to think of vertices on a 3-dimensional object is to think of vertices as corners. Now, which 3-dimensional object has 8 corners? That would be a trapezoidal prism.
