There are none because a square is made out of right angles, and a cube's faces are made out of squares.
They both have right angles, they both have sides of the same length (yes, on a cube, edges of the same length).
Do you mean "two-dimensional right angles?" If so, then each side of a cube is a square and so has four right angles.
A lot of things. For example, a cube has 8 vertices, the square pyramid has 5. A cube also has more edges and faces than the pyramid. All the faces of the cube are squares, while the pyramid only has one square face. Also, all the angles in the cube are right angles, while the angles in a square pyramid (in the usual sense of a pyramid where the apex is directly above the center of the base) are acute. In any case, they are not all right angles.
Right (90o)
No, just right angles.
No, all angles are right angles

All angles in a cube are solid right angles.
A Rubik's Cube is a perfect cube, hence it has all right angles.

there are 24 right angles in all faces of a cube

yes
yes
A cube has 6 faces, each having 4 right angles, for a total of 24 angles.
