No, not all angles in a trapezoid are congruent. A trapezoid may have two pairs of congruent angles, or may have no congruent angles.
No, not all congruent angles are 45 degrees. They only are in complementary congruent angles.
In all parallelograms, opposite angles and opposite sides are congruent. If all four sides are congruent, it's a rhombus. If all four angles are congruent, it's a rectangle. If all four sides and all four angles are congruent, it's a square.

No only regular polygons have congruent angles.
All right angles are congruent, and all straight angles are congruent.
No, not all angles in a trapezoid are congruent. A trapezoid may have two pairs of congruent angles, or may have no congruent angles.
I can't find a name for it but an example would be a trapezoid. Some might have congruent angles but not all do.
Rectangles have all angles congruent,
a polygon that has all angles congruent is an equiangular .....
No, not all congruent angles are 45 degrees. They only are in complementary congruent angles.
All rhombuses have two pairs of congruent angles (opposite angles are congruent to one another - a square is a special case type of rhombus in which all four angles are congruent).
Corresponding sides and angles are not all congruent.
In all parallelograms, opposite angles and opposite sides are congruent. If all four sides are congruent, it's a rhombus. If all four angles are congruent, it's a rectangle. If all four sides and all four angles are congruent, it's a square.

Not sure what a "quadrilaters" is. A quadrilateral is a plane (2-dimensional) figure with four straight sides. It can have all four angles different. It can have two congruent angles (kite), 3 congruent angles (no specific name), 2 pair of two congruent angles (parallelogram/rhombus), or four congruent angles (rectangle/square).
The quadrilaterals with all angles congruent are rectangles and squares. They are the only quadrilaterals in which all four angles are right angles.
