TL;DR: Thorin is half-elf, and Fili and Kili are themselves both part elf and half-human. The two young dwarves represent the union of Elves, Men, and Dwarves that once existed before Dale fell, and which will rise again.
No, Thorin belongs to the race of dwarves. Dwarves and men are different in Tolkien's universe, in that dwarves are short and portly. All dwarves are born with some semblance of a beard as well. Both races are similar in that they succumb to greed rather easily.
In The Hobbit, Thorin, a Dwarf-King in exile and twelve other Dwarves visited Bilbo Baggins at his home in the Shire. The wizard Gandalf had advised Thorin and the other dwarves to hire Bilbo as a burglar to help them steal their treasure back from the dragon Smaug.
Are Fili and Kili half-elves? Fili and Kili are not half-elf. They are the maternal nephews of Thorin Oakenshield, the dwarf, and are themselves dwarves of the line of Durin, the Longbeards.
He had trust issues, especially when it came to the elves, which had stemmed from Thranduil abandoning the towards rather than helping them with Smaug attacked, and he had the gold sickness, but there were times he was willing to take a risk.

Why does Thranduil hate dwarves?
While Thranduil didn't have a problem with Dwarves, he didn't care for a lot of Elves. In the book, Thranduil was an isolationist and with good reason. Thranduil was a Sindarin Elf, which meant that he had never been to Valinor, and he grew up in Doriath under the leadership of King Elu Thingol and Melian the Maia.
Although very little is known about the identity of Legolas' mother, she is referenced a few times in The Hobbit films, and a big part of the source of contention between Taurial and Thranduil is that she thinks him cold and unfeeling, and he thinks her naive and foolhardy.
It is later mentioned that Tauriel is a talented warrior and was therefore made leader of the Mirkwood border guards. Legolas, the son of Mirkwood's Elven king Thranduil, is indicated to be attracted to her, but as she is a lowly Silvan Elf, she does not believe herself worthy of him.
Sometime after the Battle of the Five Armies, Kili wakes up in the Caribbean with Tauriel mysteriously appearing with him. After several years of living together, the two finally marry. The duo is later shanghaied into service aboard Queen Anne's Revenge under the fierce command of Captain Blackbeard.
This has surely been asked before, but why the heck is he (a dwarrf) so tall? It's like saying why some people are taller than the average height. He's simply taller than average dwarves. If you watched or read the Hobbit, Thorin is considered very tall among dwarves, almost as tall as a human.
At Rivendell in December, T.A. 3018, Glóin told Frodo Baggins that Bombur was still alive and living in Erebor. In fact, Bombur appeared to have used some of his wealth to increase his girth – he was unable to move alone from couch to table and required the aid of six young Dwarves to lift him.
Their deaths and Thorin's did not end Durin's line, although did end the branch which had Thror, Thrain, and Thorin Oakenshield. Thorin's cousin, Dain Ironfoot, became King after Thorin's death. Dain's son, Thorin Stonehelm, became King after Dain died in the Battle of Dale. The line continued on after that.
Thorin is portrayed by Richard Armitage and Bilbo is portrayed by Martin Freeman. Fans have called them "Thilbo," but it is not canon; however this relationship is platonic in this series. An entire page was dedicated to their relationship in The Battle of the Five Armies movie guide.
Thorin became the dwarf king at a very young age after the battle. However, Thorin never married nor had any children. The young dwarf king led his people out of Dunland and they finally re-established their home in the Blue Mountains. His younger sister, Dis, later gave birth to two children, Fíli and Kíli.
Thorin II, also known as Thorin Oakenshield, was the King of Durin's Folk from T.A. 2850 until his death in T.A. 2941, being the son of Thráin II, grandson of Thrór and older brother to Frerin and Dís. Thorin led Durin's Folk of the Blue Mountains during their time in exile.
Legolas does not marry or have any children, based on the appendix of The Lord of the Rings. Regardless of who his mother was, Legolas is the last of his line. When he sails into the West at the beginning of the Fourth Age, he leaves no family members behind.
Early life. Born in TA 2341 of the Third Age, Tauriel was the daughter of Tauressar and Calmiriel. During that year when she was born, her parents went on a scouting mission to the southern borders of Mirkwood until they were ambushed by Orcs that probably spawned from the old fortress of Dol Guldur.
Kili has had one love interest: Tauriel. After he is resurrected, they marry and have a son named after his late brother, Fili. Together they are called Kiliel.
Lord of the Rings: Legolas Basically Married Gimli. Legolas and Gimli's relationship is strong in The Lord of the Rings, even though it wasn't explicitly romantic in Tolkien's source material. The members of the Fellowship in The Lord of the Rings forge an unbreakable bond while on their mission to destroy the One Ring ...
Tauriel truly threw a wrench in Legolas' life when he fell in love with her. She was brave, fierce, and a protective leader of the guard. He was meant to be the dutiful son of King Thranduil, but in loving her, he became a stubborn, masterful archer instead. He loved exploration and adventure over his duties.
From the information above, I would say that Thranduil preferred to keep himself at an arm's length from Elrond and Galadriel, the two most prominent Noldor remaining in Middle-earth; they would be on civil but not warm terms.
It is believed that after Kili dies, Tauriel becomes a lone rider and never loves again, she was so broken by the experience of losing him. Their love was real, and it was as strong as any other Middle Earth romance story. But this romance doesn't appear in the original book, so where did it come from?
While Thranduil spoke, his face transformed. Much like Darth Sidious from Star Wars, Thranduil revealed that his fair appearance was a façade. Underneath his concealing magic, he was horribly burned with nothing but bone and sinew visible. Basically, he looked like a zombie Elf.
