an infinite number; no limit
Anything that contains the line must contain every point on the line, so "a point on the line" doesn't give us any more information. You're just asking how many planes can contain the line. Now imagine setting a wood panel down on a tight-rope. How many different ways can it set there before it falls off ? A lot, right ? An infinite number of planes can all contain your line. (And all of its points.)
In Geometry
Yes because a line can lie in many planes so one we add one point not on that line, we define a unique plane.
A "perpendicular bisector" is a line. There are no triangles of any kind in a line.

No, perpendicular planes intercept at only one point. Parallel planes do not intersect at all.
exactly 1
Yes. There can be a line perpendicular to the given line at every point on it, and you know how many different points there are on it ...

In a Euclidean plane, only one.

There is only one such plane.
