There is no "the" since there are infinitely many non-parallel planes. Two non-parallel planes are planes that intersect in a line.
Yes.No. Any two planes will be contained in infinitely many planes, not "exactly one".
No. Two planes may be parallel and so may not intersect. Also, any line is the intersection of infinitely many planes, not just two.
Think you just answered your own question. A plane is a line. Two planes= two lines.
If 2 points determine a line, then a line contains infinitely many planes.

Two distinct planes will intersect in one straight line.
Two planes intersect at a line. The line where they intersect pertains to both planes. In the same manner, if infinitely many planes intersect each other at the same line, then that line pertains to the infinitely many planes.
Two.

yes, it may be the two plane intersect at one line or the two planes are coincident.
Many solids. Some are: A sphere intersected by two planes, An ellipsoid intersected by two planes, Any blob intersected by two planes, A toroid (doughnut) with a wedge removed, A double-cone intersected by two planes, A cylinder.

No, perpendicular planes intercept at only one point. Parallel planes do not intersect at all.
Two planes, one went into each tower.
