1 . Maya (Tamil acted by Nayanathara) : not typical horror / comedy but had good story line.
2. Heza (Telugu) : different story line not typical ghost revenge movies.
A lot of good suggestions. Do try out The Exorcism of Emily Rose (2005).
It really creeped me out, being a real story. Generally in horror movies something happens to someone for a reason, this one was completely random. I kept thinking WTF, what if it happens to me? I was alone in the house and it added to the scare. These days horror movies are dozen a dime. You hardly find anything good.
Some good recent ones. A lot might not be available in india, try these sites:
Watch few indonesian ones to broaden your horizon. These guys know how to visually present hell on screen 
Impetigore (2019)
I have listed this from memory. I will further update once i can access my IMDB page.
Tumbad
Veerana 😘
"No one will save you" on hotstar is another good one.
...get married....in real life...
The autopsy of Jane Doe
Hereditary
It Follows
Hell House LLC
These are the few I remember watching multiple times.
Scary Movie 1
Scary Movie 2
Scary Movie 3
Scary Movie 4
Scary Movie 5
...........Enjoy..........
BTW if want to see good horror comedy movies here's my recommendation list:
1) Tucker and Dale vs. Evil.
2) What we do in the shadows.
3) Cabin in the Woods
4) Ready or Not
5) Evil Dead series
One more: Jennifer's Body.
These movies have different ratio between Comedy and Horror. A true Horror Comedy or Comedy Horror has to have both.
