First of all you can't take cash loan of 1 lakh if you are under audit or even if you are not under audit and the department comes to know about this cash loan they can directly impose a penalty u/s 269ss which is 100% of the amount accepted in loan in the form of cash.
The limit for this transaction is 20000.
It is the limit for one person and you can accept loan from different person below this limit.
Hope you find the information helpful if you do please rate it 5 and provide your valuable feedback for my improvement.
Thank you
