I’m not familiar with any of these charities, but I think medical interventions seem especially helpful. Also, some of these charities provide economic relief in the form of food or cash to people in India who’ve been affected by the COVID-19 crisis, and that seems valuable too.
I’ve seen these charities recommended on social media:
GiveIndia’s COVID-19 page (multiple fundraisers)
Hemkunt Foundation
Mission Oxygen
Donate Oxygen India
Feeding India
Khalsa Aid
