It depends on which type of cuboid we are talking about. If it is a CUBE (a special type of cuboid), then it has nine planes of symmetry. If it is a cuboid with length, width and height all different, then it has three planes of symmetry. If it is a cuboid with two equal measurements (say width and length), then it has five planes of symmetry.
A cuboid has three orthogonal two-fold axes of symmetry through its centre. It also has three planes of mirror symmetry.
None normally because rotational symmetry is only applicable to 2 dimensional shapes such as polygons.
A figure has rotational symmetry when it can rotate onto itself in less than a full rotation.

A diamond has two rotation symmetry. It is possible to have a diamond that does have four of rotation symmetry.

Three axes of symmetry.
Yes
