Hey!
Leopard geckos are pretty simple to breed. Not sure about the other two, but that third picture looks like a Uroplatus specie, probably either Henkeli or Fimbriatus, can't see the eye that well to determine. Anyway, Uro's are some of the harder species of gecko to breed at the time, and I would only reccomend them for the experienced keeper. If you feel you're willing to take the time and money to invest in a project that will require a lot of work, I'd say go for the Uro's, but if not, I'd try something easier like Leachies or Leo's.
Thanks,
