Get the boundary of the object with bwboundaries(). Then find out if there are 6 kinks in the boundaries with the FAQ. Then see if the lengths of the sides are similar enough to be considered a hexagon rather than just some arbitrary 6-sided polygon. Also make sure it's convex by checking that the solidity is really close to 1.

How to find out the number of kinks? I searched in FAQ, but i didn't find anything regarding. So please tell me about how to find the number of kinks and how to measure the length of side

From the code the FAQ directs you to, it would be length(xStar). The distance is just the simple Pythagorean theorem, so use diff() and sqrt().
