Nearly all of Omanis are Muslim with about 75% being Ibadi Muslims, 20% being Sunni Muslims, and 4% being Zaydi Shiite Muslims. The remaining 1% includes Christianity and Hinduism.

There is only one religion of Islam, but it is divided into numerous sects. The most populous sects are Sunnis (roughly 85% of the Muslim population) and Shiites (roughly 15% of the Muslim population). There are minor sects like the Ibadi which count for less than 1% of all Muslims. Often, Westerners will consider Sufis to be a distinct sect of Islam, but while Sufism is a different form of practice (mystical vs. dogmatic), it is not a distinct sect. Most Sufis would be considered Sunnis. The more mystical sects of Shiite Islam (such as Druze, and Alawite) are often not considered parts of Islam anymore due to their abrogation of certain Islamic principles.
Yes. The Ibadi are recognized as a third legitimate sect by most Sunnis and Shiites. Additionally, there are sects like the Ahmadiyya which consider themselves to be Muslim, but this contention is challenged by both Sunni and Shiite Muslims do to the Ahmadiyya reverence for Ahmed Mirza Ghulam.
Virtually all living in Libya are Islamic; a very small amout of people however, are Christian, and even less are Jewish. There are a small amout of Ibadi Islam Berbers, however the majority of people follow Sunni Islam.

The official religion of the Islamic Empires was some form of Islam, usually Sunni Islam, but there were several Shiite, Ibadi, and Kharijite Islamic Empires at various points of history. Of course, there were significant populations (in some cases, majorities) who were Non-Muslim, often Christian, Hindu, Jewish, Buddhist, Jain, and Sikh.
Yes. While there are some Muslims who would object, all major schools of Sunni, Shiite, and Ibadi Jurisprudence agree that porcine grafts (i.e. organs/skin taken from pigs) can be used in surgery on humans. It is forbidden to eat pork, but it is not forbidden to use pigs to save someone's life.
In recent times Indian immigrants to Arabia have brought Hinduism with them and Filipino immigrants have brought Roman Catholicism with them. (While Christianity does have a historic presence in Arabia, Catholicism specifically never did.) However, prior to modern immigration, Arabia remained almost exclusively Muslim. (It is predominantly Sunni Muslim with Twelver Shiite Muslims along the northern Persian Gulf coast, Zaydi Shiite Muslim in northern Yemen, and Ibadi Muslims in Oman.)
The question as posed is nonsensical. A person in a more expansive religious group cannot convert to a smaller group within that religion. Ismaili Islam is one form of Shiite Islam. The equivalent question in another religion would be "How can a Christian convert to Catholicism?" or "How can a Theravada convert to Buddhism?" If a non-Ismaili Muslim (such as Sunni, a Zaydi Shiite, a Twelver Shiite, an Ibadi, etc.) wants to join Ismaili Islam, all they need to do is find an Ismaili congregation and join their community.
I haven't really heard about the sectors of Islam. There are actually five pillar of Islam, pillar means the basic 5 obligations of every Muslim if he had the capacity. The 5 pillars are;Shahada (God in one)Salat ( Namaz)Fasting in RamazanZakatHajj (pilgrimage)If you are refering to sects of Islam, there are three main ones: Sunni (about 85%), Shiite (about 15%), and Ibadi (
Oman is actually majority-IBADI, which is a minority sect in Islam that represents less than 1% of all Muslims.
