If two lines are not coplanar then they are neither intersecting nor parallel?
CorrectParallel lines as well as intersecting lines must be coplanar (in Euclidean geometry not quite sure about hyperbolic geometry...).Lines in space which neither are coplanar nor intersecting are called "skew"
Are vertical angles formed by two intersecting lines coplanar?
Yes. They're in the plane defined by the two intersecting lines.
Is intersecting lines always coplanar?
Yes. The two lines define a plane which they both belong to.
Are any two noncoplanar lines skew?
I guess they are. If they're parallel or intersecting, then they're coplanar.
Can two lines be coplanar?
yes, two lines can be coplanar.
Can two intersecting lines be non-coplanar?
No.

Yes

Can two lines be coplanar?
yes, two lines can be coplanar.
Why can two lines be coplanar?
Two lines are not always coplanar. If they intersect or are parallel, thenthey're coplanar. But if they're skew, then they're not coplanar.Example of parallel lines in space:The top and bottom edges of a wall in your room.Example of intersecting lines in space:The top edge and left edge of a wall in your room.Example of skew lines in space:The top edge of one wall and the bottom edge of a wall next to it in your room.
How many planes can contain intersecting lines?
I'm not entirely certain what you're asking. Any pair of intersecting lines are of necessity coplanar, (assuming Euclidean geometry) though.
Are two lines that are not parallel coplanar and do not intersect?
are two lines that are not parallel, coplanar, and do not intersect
How many pairs of vertical angles are formed by 3 coplanar lines intersecting at one point?
Eight.
Two lines in intersecting planes are skew.?
Two lines in two intersecting planes can be parallel, intersecting, or skew.
