Can you explain to me why those compounds are identical and why the last compound is a meso compound?

The top compounds are the same because they are the exact same chair structure flipped, meaning that all axial positions become equatorial and vise versa. The bottom structure is easier to recognize as meso if you were to look at the ring itself but the gist is that both hydrogen atoms face up and both bromine atoms face down meaning that the ring would have a line of symmetry between the two bond sites.

Hey there! I've illustrated below how I converted into a bondline structure to easily understand the relationship between the molecules.

I hope this helps!
