It is concave because it is going in so it is going in the cave
A regular hexagon and 3 classes of convex hexagons, plus concave hexagons will tessellate.
concave
It can be convex or concave.
A rhombus is an equilateral parallelogram. As such, it is neither concave nor convex.

No
A regular hexagon and 3 classes of convex hexagons, plus concave hexagons will tessellate.
It depends on what the angles are. If any of the angles have measurements greater than 180 degrees, it is concave. If all angles are less than 180 degrees, then it is concave. For example, a regular hexagon has six 120 degree angles, so it is convex. If there was a hexagon with five 90 degree angles and one 270 degree angle, it would be concave.
A concave irregular hexagon can have up to 6 right angles. A convex irregular hexagon can have up to 3 right angles.

concave is inward, convex is outward concave is inward, convex is outward
convex and concave
The answer depends on what you mean by size: its area (more likely) or perimeter. In either case, the answer depends on what information you have about the hexagon: whether it is regular, irregular but convex, or concave.
If it's a regular hexagon, it can't be concave. If it's an irregular hexagon,then it can be concave if it wants to, but it doesn't have to be.
