There are two possible answers; if the line is crossing the plane at an angle, then the line and the plane only intersect at one point. However, if the line is part of the plane, then the entire line intersects with the plane, and there are an infinite number of intersecting points.
The intersection of two planes is a line. (or a massive explosion...lol)
point of intersection.
Yes, except when the line is in the plane. In the latter case, they intersect at each point on the line (an infinite number).

No, 2 planes may only intersect at a line, a plane, or not at all. THREE planes may intersect at a point though...
Yes. If two planes are not coincident (the same plane) and are not parallel, then they intersect in one straight line.
The intersection of three planes can be a plane (if they are coplanar), a line, or a point.
If you mean "only one plane can pass through another plane and through a point that is not on the line formed by the intersection of the two planes," the answer is "no." If you rotate the plane about the point, it will still intersect the line unless it is parallel to the line. By rotating the plane, you have created other planes that pass through the unmoved plane and through the point that is not on the line formed by the intersection of the two planes.

No, two planes do not intersect in exactly one plane unless the planes are exactly overlapping, making one plane. In Euclidean Geometry two planes intersect in exactly one line.

Yes. If two planes are not coincident (the same plane) and are not parallel, then they intersect in one straight line.
