Any non-square rhombus. From Wikipedia:
Every rhombus is a parallelogram, and a rhombus with right angles is a square. (Euclid's original definition and some English dictionaries' definition of rhombus excludes squares, but modern mathematicians prefer the inclusive definition.)
(And as long as you're just talking about the length of those sides -- which is the only sensible interpretation of the question -- it's clearer to call them "equal" than "congruent".)

A square. Parallelogram * * * * * No. It is a rhombus and a square is a special case of a rhombus. A parallelogram does not have four congruent sides, but two pairs of sides that are congruent to one another.
Angles and sides are congruent when they are identical. A shape with four identical sides and angles is a square.

No, not every quadrilateral with four congruent sides is a square. While a square does have four congruent sides, it also has four right angles. A shape with four congruent sides that does not have right angles is classified as a rhombus, which is a type of quadrilateral but not a square.
It has four congruent sides.
