Among those who participated in the Kurukshetra war only ten were alive after the war. Seven from Pandavas side and three from Kauravas(Dhartarashtras) side.
They are: Five Pandavas, Vasudeva, Satyaki, Ashvatthama, Kripa and Kritavarma
The following words by Dhritarashtra contains the count of the people survived after war from both sides
'Alas! I have heard that the war hath left only ten alive: three of
our side, and the Pandavas, seven, in that dreadful conflict eighteen
Akshauhinis of Kshatriyas have been slain! All around me is utter
darkness, and a fit of swoon assaileth me: consciousness leaves me, O
Suta, and my mind is distracted."
[Section I, Adi Parva, The Mahabharata]
The following words by Ashvatthama contains the names of people survived after the war
"If, O Duryodhana, thou hast
any life in thee still, listen to these words that are so pleasant to
hear. On the side of the Pandavas, only seven are alive, and among the
Dhartarashtras, only we three! The seven on their side are the five
brothers and Vasudeva and Satyaki; on our side, we three are myself
and Kripa and Kritavarma! All the sons of Draupadi have been slain, as
also all the children of Dhrishtadyumna! All the Pancalas too have
been slain, as also the remnant of the Matsyas, O Bharata! Behold the
vengeance taken for what they had done! The Pandavas are now
childless! While buried in sleep, the men and animals in their camp
have all been slain! Penetrating into their camp in the night, O king,
I have slain Dhrishtadyumna, that wight of sinful deeds, as one kills
an animal."
