There is no specific name. For example, if you number the sides of a regular hexagon sequentially from 1 to 6, then sides 1 and 3 are not parallel but there is no specific name for that pair. In the context of the hexagon they do not meet - even if they do so way outside the hexagon.
If they do meet up in the context of the shape, then they will be adjacent or intersecting sides.
It can do. The non-parallel sides of an isosceles trapezium will be equal. Also, one of the non-parallel sides could be equal to one of the parallel sides.
A trapezium has two parallel sides (of unequal length) and two non-parallel sides.
Yes the non parallel sides of an isosceles trapezoid are congruent
Parallel sides are sides that (in a plane) do not meet whereas sides which are not parallel do meet at some point at an angle greater than 0°.
Any polygon with four or more sides can have a pair of parallel sides. It is also possible to to have non-polygonal shapes - eg a cigar-shape - that has parallel sides.
They are the lateral sides or the transverse sides.
The legs or transverse sides.
the Legs
legs
There is no generic name. Any polygon with 4 or more sides can have 2 parallel sides. There are also non-polygonal shapes that can have parallel sides: for example, a circle that is stretched out into a cigar shape can have two parallel sides.

Trapezoid
A trapezoid has two parallel sides and two non parallel sides.
Yes the non parallel sides of an isosceles trapezoid are congruent
All regular polygons with an even number of sides. Irregular polygons with an odd number of sides can have parallel sides. There are also non polygonal shapes that can have parallel sides.
The two parallel sides are called the bases, and the two non-parallel sides are the legs. If you call any other pair of sides the bases, the formula for the area of the trapezoid will no longer work.
