No, planes intersect at a line.
They intersect at a point
The angle between two planes when the planes intersect at a point is the acute angle fixed by the normal vectors of the planes.
an infinite number; no limit
Nothing HAPPENS! They can intersect in a point or a line.
No, planes intersect at a line.
yes, three planes can intersect in one point.
No, perpendicular planes intercept at only one point. Parallel planes do not intersect at all.
No, they can intersect at infinitely many points.
Two planes intersect at a line
They intersect at a point
No, 2 planes may only intersect at a line, a plane, or not at all. THREE planes may intersect at a point though...

No.

yes two lines intersect to form a point two planes intersect to form a line
