Yes- planes contain infinitely many points and every pair of points in plane determine a line in that plane, so every plane contains infinitely many lines.
Skew lines.
No. Skew lines are lines in different planes that are parallel.
Infinitely many planes may contain the same three collinear points if the planes all intersect at the same line.
They're either parallel lines or skew lines.
If the two lines have a common ponts.

Yes, and in fact it is very likely that two planes will contain exactly one identical line. There are three possibilities:The planes are parallel, but not identical, in which case they contain no identical lines.The planes are not parallel, in which case they contain exactly one identical line.The planes are identical, and contain an infinite number of coplanar lines.
Two intersecting straight lines uniquely define one single plane.
No, two straight lines can intersect at only one point and that is their point of intersection.
Ponts's population is 2,803.

I'm not entirely certain what you're asking. Any pair of intersecting lines are of necessity coplanar, (assuming Euclidean geometry) though.
The area of Ponts is 30.5 square kilometers.
