no, just look at the edge of a box.

Planes do not intersect at a point. They intersect at a line. Those are lines that intersect at a point.

There's two possibilities. Two planes intersect in a line, or they don't intersect at all, because they are parallel.

No. Planes can sometimes intersect at a line segment. Planes don't always necessarily intersect either, they can be parallel.
