Two lines in two intersecting planes can be parallel, intersecting, or skew.
One.
If they are straight lines, then they define a plane in which both lines lie.
the answer would have to be skew
Not really. A railroad intersection would be an example of two lines intersecting. An example of two planes intersecting would be the ground and the side of a building or the ground and the railroad crossing sign post.

I'm not entirely certain what you're asking. Any pair of intersecting lines are of necessity coplanar, (assuming Euclidean geometry) though.
Yes, two lines in intersecting planes are never skew. Skew lines are defined as lines that do not intersect and are not parallel, typically found in different planes. Since the two lines are in intersecting planes, they can either intersect or be parallel, but they cannot be skew.
Two intersecting straight lines uniquely define one single plane.
No, two lines in intersecting planes cannot be skew lines. Skew lines are defined as lines that do not intersect and are not parallel, typically existing in different planes. However, if two lines are in intersecting planes, they must either intersect at some point or be parallel to each other. Thus, they cannot be classified as skew lines.
Intersecting planes!
Exactly one plane in each case.
Skew Lines. :)
Two intersecting lines can always cover three non-collinear points.
One.
Two lines in intersecting planes are never skew. Skew lines are defined as lines that do not intersect and are not parallel, which occurs only in three-dimensional space. However, since the planes intersect, any lines within those planes can either intersect or be parallel, but they cannot be skew.
