Just look at the conversion chart, everything is listed here:
LICENSING RULES AND REGULATIONS
For multi endorsement DGCA requirements are 10hours on the A/C(including test/check) and make sure you get atleast 5 hours of night time. Some guys were rejected 5-6 months ago and were told to bring the breakdown of hours showing what i mentioned above.
But most airlines nowadays are asking for 25 hours of multi(10 of which can be on a Sim).
