Two trapezoids
A concave hexagon is a hexagon that has one or two reflex angles. With one reflex angle, it will resemble a chevron - like a stripe on a police or army uniform, or the letter V which has thickness. With two reflex angles, it will resemble an hourglass with straight sides.
An Irregular hexagon looks like anything that has no bended angles/sides. Also it only has 6 sides/angles.
A concave hexagon is one in which one or two interior angles are greater than 180 degrees. With one reflex angle, it would look like a chevron.The browser used here is pretty grim for graphics but, the following is a crude rendition. Ignore the dots - they are required to get the spacing approximately right!_____\.......\..\.......\../......//____/
Yes, it looks like an arrowhead and is called a concave quadrilateral.
A bit like a chevron or an arrowhead.

Yes, a regular hexagon has ALL sides the same length and ALL angles equal. If you flatten it somewhat (like the profile of a lens) then the sides may still have the same length but some angles will be larger than others if opposite angles are the same than there will be symmetry. (there are many other options to retain symmetry in a hexagon this is but one)
There are four types of concave (not cocave) hexagons:one reflex angle,two reflex angles, opposite one another,two reflex angles with one next-but-one to another,three reflex angles alternating.This site is not suitable for displaying images.
a hexagon with a refle angle
Any that you like, acute, right, obtuse or reflex. The only restriction is that all six of them must add up to 720 degrees.
Yes. A non-convex hexagon with 3 main points like a triangle will only have 3 lines of symmetry.
It is not possible to have a hexagon with all right angles.
A hexagon. Possibly a hexagon with one reflex angle.
An Irregular hexagon looks like anything that has no bended angles/sides. Also it only has 6 sides/angles.
Oh, dude, a regular hexagon has six sides, so it has six lines of symmetry. Each line of symmetry represents a different way you can rotate the hexagon and have it look the same. So, the order of rotational symmetry for a regular hexagon is 6. Like, it's symmetry, but make it hexagonal.
It is difficult to illustrate the answer but I'll try a description. Start with a regular hexagon. All sides equal, all angles equal, six lines of symmetry. Squash the top down so that the middle vertices spread outwards. You will now have a shape with two lines of symmetry: one horizontal: halfway up the hexagon and one vertical: halfway across. Now take a chunk out of the middle of the top (or bottom, but not both) side and re-join the ends. That will get rid of the horizontal line of symmetry and all you are left with is the one vertical line.
