If a triangle does not have the same length side as another triangle the sides are not congruent.

This shape would be a square.
A trapezium with all its sides congruent is an impossible shape.
This is a parallelogram. The first requirement is 2 pairs of congruent sides where the congruent sides are not adjacent. This is like a rectangle (excluding a square) that has two pairs of congruent sides where the congruent sides are not adjacent. But the angles are not all congruent (as set in the question) which pushes the shape into the "next less regular" shape, the parallelogram. The angles will not all be congruent, but it will have 2 pairs of congruent angles. There is no way to avoid the 2 pairs of congruent angles because of the requirement that the shape must have 2 pairs of congruent sides (the first requirement).
Rectangle
yes. congruent means equal size and shape. a square has 4 sides all congruent to each other.
