One known Buddhist religious leader is Ashin Wirathu. Also, two other Buddhist religious leaders include Monshu and the Dalai Lama.
Luis Fortuño is the Governor of Puerto Rico at this time.
There are different religions in Ireland so there is no single answer to that. The leaders of those different religions would have different titles. All the main world religions in the world, like Christianity, Islam, Judaism, Buddhism, Hinduism etc., are all found in Ireland.
The answer to this depends on which tradition of Buddhism is being discussed. For example, the leader of Tibetan Buddhism (and perhaps the most respected Buddhist in the world) is the Dalai Lama. In other Buddhist groups, the titles and positions vary widely, just as they do in Christian groups.
There are no leaders in Buddhism. The only leader exist in this world is Dhamma which are the teachings of Thathagathe Gouthame Buddha who rediscovered Dhamma. Dhamma is the Guru of the disciples of Thathagathe Gouthame Buddha and he also considered Dhamma as his Guru. There can be popular figures with various titles that is for recognition and there can be teachers who explain and pass down Dhamma to disciples but there is no leader but Dhamma itself.
