Two lines are not always coplanar. If they intersect or are parallel, then
they'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.
yes, two lines can be coplanar.
are two lines that are not parallel, coplanar, and do not intersect
No. If two lines intersect, then they're definitely coplanar.
No, not always. Skew lines are never coplanar, but parallel lines are.
Two coplanar lines that never intersect are called called parallel lines.
Two lines that are perpendicular to the same plane are coplanar. This means that they lay on the same plane.

Parallel lines.
Parallel Lines or Skew Lines.
Coplanar lines that do not intersect are parallel. Non-coplanar lines that do not intersect are called skew lines.
