Can I withdraw my entire pf while remain in the company?

75 percent max. I withdraw 90k when pf was 1 lakh something....

No,You can only withdraw partially for medical reason,higher education , construction of house etc

I withdrew 96k when my available pf balance was 1.2lakh.....I chose buying a house option..

How many years in tcs you are having ?? Seems it should be minimum 5 years for any reason

I took house loan , can I take partial pf to close some house loan ?

No, I think max 50-60% depending on the requirement
