There are more than two: A parallelogram has two sets of parallel line segments which may be of unequal length; A rectangle is a parallelogram that has line segments that meet at right angles; A rhombus has to sets of parallel line segments which are all of the same length; A square is a rhombus which has line segments meeting at right angles, or stated differently a square is a rectangle which has all line segments of the same length.
They can not be line segments on the same line, but they can both be line segments.
Parallel line segments? Or parallels maybe. In french at least it's that way, so I'm assuming it's the same for english. :)
it depends on how you place it, they can be. all a line segment is is a straight line, if you have two you can have parallel or crossing lines.
I classify a parallel line as two line segments that will never intersect if the line kept going. They are perfectly straight and even.
no

Line segments that do not intersect are parallel lines
Their slopes are equal.

First, lines and rays cannot be congruent because they do not have both end points defined. Not having an end point define means we cannot talk about their length so they can't be congruent. Line segments, however, can be congruent. Congruent line segments NEED NOT be parallel.Furthermore, if two line segments are parallel, that does not mean they are congruent since parallel line segments may not have the same length.Congruent line segments would be ones that are the same length.

Parallel lines
There is no specific name - other than what you used: "a pair of parallel line segments".
Letters that have parallel line segments are H, E, F, M, and N
