a double triangle
No. You could, for example, have a square and a rhombus with sides twice as large.
Similar polygons have the same size angles, but the side lengths are proportionally different, thereby the area is different. Congruent polygons have the same size angles, the side lengths, thereby the area is the same.

True
They are called regular polygons
Yes, those polygons which have angles of 90 degrees and equal side lengths are called squares; those with uneven side lengths are called rectangles.
