The first one is defiantly pronounced like Coo (like a stereotypical owl noise) and then cullin, like the cullin family in the Twilight movies. Coo-cullin.
The second one looks pretty okay to me. pronounce as spelt would be my advice.
the third is pronounced ah-ielle (i think), dubh is pronounced like the word dove, with a u instead of an o, dubh (which is the irish word for black), and dedach is pronounced day-dach, with emphasis on the ach, lick a hacking noise.
the forth, like the second, sounds like it's spelt to me :)
hope i helped :)
