A prism??? O.o sounds like it to me anyway...
An object with 2 congruent pentagons at opposite ends connected with 5 rectangles is a pentagonal prism.
Each end of the prism will have a parallel 6 sided hexagon joined together by 6 rectangles.
1 hexagonal prism = 8 faces (2 hexagons, 6 rectangles), 18 edges, 12 vertices.
There is no 3D shape with 6 faces: 4 rectangles and 2 triangles. See the link for all forms of hexahedra.

how about 2 hexagons connected with 6 rectangles

6 shapes. There are the 4 long rectangles and 2 squares or smaller rectangles.
An octahedron shape is one which has 8 faces. Since it is a prism it must be a hexagonal prism (2 hexagons and 6 rectangles = 8 faces). And a hexagonal prism has 2*6 = 12 vertices.
Any 3D shape with a constant cross-section; in other words, a 2D shape stacked on top of itself, like a triangle on a Toblerone box. But it need not be a triangular shape that is stacked. A rectangular 2-d shape would give a cuboid. Any poygonals shape can be stacked for a prism. Not a piramid, or pyramid even, which is not a prism!
Many things have 2 sides that are congruent, including isoceles triangles, any regular polygons or polyhedrons, rectangles, etc.
