Dharamkot to Singapore Flight

I'm intending to go to HP at Dharamkot for 3 weeks in July.

To get to Singapore, I will be needing to change my flight at IGI

Solo female traveller and speaks Hindi fluently but never been to India before

Born and raised north Indian outside of India

Would I be safe doing the airport transfer myself? It says self-transfer on the flight. The flight is a morning-afternnon flight and I'll be landing in Singapore in the evening
