it has seven sides and must look like a regular hexagon
no, because a quadrlateral has 6 sides and a hexagon has 4
It would look a bit weird, but the only way to achieve this is by curving the sides or by making a concave hexagon.

It is called a hexagon (pronounced like: hehx-a-gon).

doesn't look like a hexagon, a shape with six sides only that are any lenght

An Irregular hexagon looks like anything that has no bended angles/sides. Also it only has 6 sides/angles.

No such thing . . . A rectangle is a four sided polygon and a hexagon is a six sided polygon. How they could mix, I have no clue.
From a bird's eye view it would look like a regular 6 sided hexagon.

It looks like the shape of a STOP sign except that it has only six sides.
A regular hexagon cannot make a 3d figure because a regular hexagon tessellates. As a result t will make a large tiled surface. If the hexagon is not regular then the side elevation will depend on the shape of the hexagons and how they are configured.
