In the Marvel Universe, the Hindu Gods belong to a race called the Daevas. They live in Nirvana and besides immortality, have a host of superhuman powers.
Vishnu
The leader of the Hindu pantheon, Vishnu also has a seat at the Council of Godheads. The strongest Marvel Hindu God confers with the Norse and Greek Gods, Odin, and Zeus.
Brahma
Endowed with both brains and brawn, Brahma is a chief figure of the Daevas race. Part of the three chieftains of the Hindu pantheon, his physiology makes him more powerful than ordinary Gods.
Shiva
The third member of the pantheon, Shiva is the god of destruction and transformation. He first appeared in Thor #301, but it was later retconned that it was Indra, disguised as Shiva.
Indra
In the Marvel comics, Indra's origin is slightly murky but he is presented as the most powerful warrior god in the pantheon. Indra has appeared in issues like Chaos War.
