Ragnarok is not a god, but rather a series of events in Norse mythology that involves the end of the world, with battles and destruction ultimately leading to the rebirth of the world.
Ragnarok wasn't a god/or a being. In Norse Mythology Ragnarok, was the predestined death of the Germanic Gods. Ragnarok marks the end of the old world and the beginning of the new.
I assume you are talking about surviving Ragnarok, and yes, there are a few. The more important ones are Odin's sons, Vali and Vidar.
In Norse Mythology, it was Víðarr who ultimately killed Loki during Ragnarok. Víðarr avenged the death of his father, Odin, by slaying Loki with his bare hands.
Loki was a god in Norse mythology. He was seen as a trickster. The other gods did not like him. He was half-giant/jotun/troll. His three children ( Hel, The Midgard Serpent, and Fenrir) played a major part in Ragnarok.
The Norse god Fenrir, also known as the Fenris Wolf, was more of a monster than a god, although he was thought to be the eldest son of the god Loki. The position of Fenrir was as an opponent of the gods. Fenrir was expected to fight on the side of the Frost Giants when the time came for the Norse apocalypse. Of all the agents of destruction faced by the Norse gods, Fenrir was thought to be the most terrible.
In Norse mythology Odin was a god, but he was devoured by Fenris (Fenrir the wolf) during the battle of Ragnarok, and so technically is no longer one. Odin was the "Allfather" of Norse mythology, and the first of the Aesir (gods) to be born. Ironically, as the eldest, strongest and wisest, he was also the first to die when the final battle came.
Loki is the Norse god of fire.
