9 planes in Cube 3 Planes in Cuboid
There is no "the" since there are infinitely many non-parallel planes. Two non-parallel planes are planes that intersect in a line.
Infinitely many planes.
Yes.No. Any two planes will be contained in infinitely many planes, not "exactly one".

In and along the crystal planes.
Cristal are fundamentally anisotropic. They are geometrically organized in planes that are denser than other direction. When acid etch a crystal, it began where it's easier, by the planes directions where the atoms are the most distant from each other. This process highlight's the crystal planes.
In case of sodium chloride crystal we have sodium positive ions and chloride negative ions have been arranged in a perfect order. As we break the crystal then it gets broken only at some definite planes containing these ions. Hence these planes have been named as cleavage planes. The other name for these planes is lattice planes.
Covalent network solids are generally not malleable. They have crystal structures that lack obvious glide planes and the covalent bonds are difficult to break and remake. This is a contrast with the metals where many of the crystal structures have glide planes and metallic bonds are relatively easy to break and remake.
Because
No.
Registeel doesn't exist in crystal version.
Fluorine Form Molecules or Crystal lattices or exist as a single atom.
These are called striations.
Yes of course they do!
There is no such thing as a Crystal Onix. It only exist in the anime.
