Infinitely many.
Infinitely many planes.
Yes.No. Any two planes will be contained in infinitely many planes, not "exactly one".

A sphere has an infinite number of planes of symmetry. The plane must include the center of the sphere, but it can tilt at any angle. The question is the same as asking "How many planes can be drawn through one point ?" The answer is: An infinite number. And as long as the point is the center of the sphere, each plane is a plane of symmetry of the sphere.
Infinitely many.
Infinitely many planes.
I have a feeling that I'm wrong but i guess that 2 planes can pass through 2 points

four.
There are 56 such planes.
No, perpendicular planes intercept at only one point. Parallel planes do not intersect at all.
