There are many, many Demigods in Hindu filosofy. It's said that there are around 33.000.000! That's a lot. There is a Demigod or Demigoddess for every aspect of the physical and non physical creation.
I understand that some may take offence because they are worshiping lord Shiva or Kali as there Supreme Personality of Godhead. The view on the Demigods below, is the view, that of the Chaitanya Vaishnava, tradition. The Hare Krishna's do not worship demigods, they only worship Krishna.
Some of the most worshiped Hindu Demigods are Lord Shiva, Lord Brahma, Durga, Kali, Lord Ganesha.
Lord Shiva
Quote by Srila Prabhupada
Brahma is said to be the highest living entity within the universe, and Lord Shiva’s position is higher than that of Lord Brahma.
Brahma is the creator of this universe, every universe has a different Brahma, some have 2 heads, some 3 or more. The duration of one day for Brahma's takes trillions upon trillions of years as we know them. But he does not live forever, he dies, just like us.
Durga or Parvati, is the wife of Lord Shiva. She can create, maintain and annihilate any universe.
We live, according to the Hindu calendar, in the age of kali yuga. Kali rules over maya. Maya in sanskrit is ma=not, ya=this. She controls time. She is fearsome, and worshiped by many hindu's, for material things.
Ganesha is best-known and widely worshipped in the Hindu tradition. Ganesha is the remover of spiritual and material obstacles.

All this information was taught to me during the 3 years that i lived within the Hare Krishna movement. I had to refresh a little, because it's 15 years ago sinds i lived there, so I looked over some Hare Krishna sites.
Thanks for reading, i appreciate your follows :-)
