I assume you want to see six different polygon shapes, each made from four congruent squares. If so, look at the attached picture.
A clear statement of a well-formed problem will get you halfway (at least) to the solution. If you don't understand the problem well enough to write it down, then it will be difficult for you or anyone else to solve it. There's no such thing as a "different congruent polygon." Congruent polygons are identical in size and shape.
