Rectangular prism
A rectangular prism does not need to have any square faces. All its faces may be rectangular in shape. However, it may also have two or four square faces, yet still be a rectangular prism.
No unless it is in the shape of a cube
This depends on whether or not the prism is a rectangular prism or not. Simple shape prisms (rectangular, triangle, octagonal, hexagonal) all have rectangular faces.
Every rectangular prism does. That includes cubes.
They are all rectangular but there can also be 4 rectangular faces and 2 square faces. Always 6 in total.

A tissue box is typically in the shape of a rectangular prism, which is a three-dimensional shape with six faces, all of which are rectangles. The base and top faces of the tissue box are congruent and parallel, as are the side faces. The edges where the faces meet are all right angles.

A hexahedron of which a parallelepiped is a special case. A cuboid is a special case of a parallelepiped and a cube is an even more specific example. All the faces are quadrilaterals. A rectangular dipyramid (two rectangular pyramids stuck together along their rectangular faces) is another example. All faces are triangular.
Look at the prism. If all faces are rectangular (or square) then so are the bases. Otherwise they are the two congruent parallel faces that are not rectangular. Look at the prism.

A parellelepiped (pronounced parellel pie ped) is any shape with 6 faces and 12 edges. A cuboid, also called a rectangular parallelepiped, is a parallelepiped of which all faces are rectangular. A cube is a cuboid with square faces. A rhombohedron is a parallelepiped with all rhombic faces. A trigonal trapezohedron is a rhombohedron with congruent rhombic faces. http://commons.wikimedia.org/wiki/File:Parallelepipede.png
