Here are some names of mongolian tribes,
Kerait
The Kerait were a tribe of mixed Mongol and Turkic ancestry. However, names and titles of Kerait rulers imply that they primarily spoke a Turkic language.[2][3][4][5] They were partly influenced by Nestorianism.[3][6] Prominent christian figures were Toghrul and Sorghaghtani Beki.
Merkit
The Merkit were a Mongol tribe who opposed the rise of Temüjin, and kidnapped his new wife Börte. They were defeated and absorbed into the Mongol nation early in the 13th century. Other than with most other tribes, that was the end of their line of ancestry
The Tayichiud were a Mongolian tribe, mostly residing in the centre of Mongolia and southeastern area.
The Tayichiud were rivals of the Naimans and several other tribes. In the Secret History of the Mongols, they are portrayed as bitter enemies of Genghis Khan
The Naimans, also Naiman Turks[1][2] or Naiman Mongols[3], (Mongolian: naiman, "eight"[4], Kazakh: Найман) was a Mongolian name given to a group of people dwelling on the steppe of Central Asia, having diplomatic relations with the Kara-Khitai, and subservient to them until 1177. The Naimans are most often classified as a Turkic people from Sekiz Oghuz (means 'Eight Oghuz' in Turkic),[5][6][7][8] but there are also sources that count them as Mongols.[8] Like the Khitai, many of them were Nestorian Christians.
More than 400,000 of the Kazakh population are Naimans (see Modern Kazakh tribes or Middle Juz). They originate from eastern Kazakhstan. Some Naimans dissimilated with the Kyrgyz and Uzbek ethnicities.
There is a small population of Naimans in Afghanistan. They belong to the Hazara tribe and reside in a small village called Naiman. They are Sunni Muslims.
The Öngüd, or Öngüt, were a Turkic[1] tribe, active in Mongolia around the time of Genghis Khan (1162–1227.[2] Many members were Nestorian Christians.[3] They lived in an area lining the Chinese Great Wall, in the northern part of the Ordos and territories to the northeast of it.[4] They acted as wardens of the marches for the Chin to the north of the province Shansi.[5]
When the Öngüt chief Alakush-tegin was killed for supporting the Mongols against the Naimans, Genghis Khan took the family under his protection and gave the son one of his own daughters in marriage.
Many famous post-Genghis Mongols are of Öngüd descent, including the well-known monk, traveler, and diplomat, Rabban Sauma (1220–1294).
A number of Öngüd were said to have been converted to catholicism by John of Montecorvino (1246–132

and here is some information abouth Temujin
Temüjin had three brothers named Khasar (or Qasar), Khajiun, and Temüge, and one sister named Temülen (or Temülin), as well as two half-brothers named Bekhter and Belgutei. Like many of the nomads of Mongolia, Temüjin's early life was difficult. At nine years old, as part of the marriage arrangement, he was delivered by his father to the family of his future wife Börte, who were members of the Onggirat tribe. He was to live there in service to Deisechen, the head of the household, until he reached the marriageable age of 12. While heading home, his father was poisoned during a meal with the neighbouring Tatars, who had long been enemies of the Mongols. Temüjin returned home to claim the position of khan. However, his father's tribe refused to be led by a boy so young. They abandoned him and his family, including his mother Hoelun, leaving them without protection.
For the next several years, Temüjin and his family lived in poverty, surviving primarily on wild fruits, marmots, and other small game hunted by Temüjin and his brothers. It was during one hunting excursion that 13-year-old Temüjin killed his half-brother, Bekhter, during a fight which resulted from a dispute over hunting spoils.[7] This incident cemented his position as head of the household.
In another incident in 1182 he was captured in a raid and held prisoner by his father's former allies, the Ta'yichiut. The Ta'yichiut enslaved Temüjin (reportedly with a cangue), but with the help of a sympathetic watcher, the father of Chilaun (who would later become a general of Genghis Khan), he was able to escape from the ger by hiding in a river crevice. It was around this time that Jelme and Bo'orchu, two of Genghis Khan's future generals, joined forces with him. Along with his brothers, they provided the manpower needed for early expansion. Temüjin's reputation also became relatively widespread after his escape from the Ta'yichiut.
At this time, none of the tribal confederations of Mongolia were united politically, and arranged marriages were often used to solidify temporary alliances. Temujin grew up observing the tough political climate of Mongolia, surrounded by tribal warfare, thievery, raids, corruption and continuing acts of revenge carried out between the various confederations, all compounded by interference from foreign forces such as the Chinese dynasties to the south. Temüjin's mother Ho'elun taught him many lessons about the unstable political climate of Mongolia, especially the need for alliances.
As previously arranged by his father, Temüjin married Börte of the Konkirat tribe around when he was 16 in order to cement alliances between their respective tribes. Börte had four sons, Jochi (1185–1226), Chagatai (1187—1241), Ögedei (1189—1241), and Tolui (1190–1232). Genghis Khan also had many other children with his other wives, but they were excluded from the succession, and records of daughters are nonexistent. Soon after Börte's marriage to Temüjin, she was kidnapped by the Merkits, and reportedly given away as a wife. Temüjin rescued her with the help of his friend and future rival, Jamuka, and his protector, Ong Khan of the Kerait tribe. She gave birth to a son, Jochi, nine months later, clouding the issue of his parentage. Despite speculation over Jochi, Börte would be his only empress, though Temüjin did follow tradition by taking several morganatic wives.[8
Religion
Genghis Khan's religion is widely speculated to be Shamanism or Tengriism, which was very likely among nomadic Mongol-Turkic tribes of Central Asia. But he was very tolerant religiously, and interested to learn philosophical and moral lessons from other religions. To do so, he consulted among others with Christian missionaries, Muslim merchants, and the Taoist monk Qiu Chuji.
