Hello,
.
Yes, here is the list of famous  computer  scientist from India.
.

• Abdul waheed khan
• Ajay kapor
• Amar Gupta
• Arvind Joshi
• Avinash kak

.
as you only asked for 5 members. I have listed only 5 but there are many other famous scientists in India.
.
NOTE: COMPUTER SCIENTISTS AREN'T RANKED, BECAUSE ALMOST ALL THE CS HAVE AN EQUAL WORK OR EQUAL KNOWLEDGE . SO IF ONE CAN DO A DIFFERENT THING EVEN THE SAME THING CAN BE DONE BY OTHER SCIENTISTS.
.
so the above are some of the famous ones.
Hope it will be helpful
thank you
