It's possible but usually not. But any two regularones are definitely always similar.

No. They're always in the same ratio.
The exterior angle of each hexagon can be any measure you like, including reflex angles. Two such hexagons can be joined together at any pair of angles that are smaller than 180 degrees. So the exterior angle formed can range from 0 to 360 degrees (excluding the two bounds).
No. Two regular hexagons are always similar to each other, but two random hexagons are not necessarily similar.

No, they are not.
All six-sided two dimensional figures are hexagons.
