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.
Never.
In 3d space, two planes will always intersect at a line...unless of course they are the same plane (they coincide). Because planes are infinite in both directions, there is no end point (as in a ray or segment). So, your answer is neither, planes intersect at a line.
No, planes intersect at a line.
yes, three planes can intersect in one point.

No, 2 planes may only intersect at a line, a plane, or not at all. THREE planes may intersect at a point though...

The intersection of two planes is never a point. It's usually a line. But if the planes have identical characteristics, then their intersection is a plane. And if the planes are parallel, then there's no intersection.
No.

No, perpendicular planes intercept at only one point. Parallel planes do not intersect at all.
