How do I achieve FIRE?

Background-21 yr. old male with a mother and a younger sibling. Dad (48m) held a high position at a firm and had just started a side-business 1 month before succumbing to cancer last year. Since then, we receive monthly compensation of 7 lakh. Our current assets and monthly expenditure are as follow:

monthly expenditure-1.75 LPM

1cr in jewelry

1.7 cr in properties

70 lakhs in liquid

80 lakhs in F.D

1.5 cr in policies

We are able to save 70-75% of our income, we have a corpus target of 5cr in the next 5+years.Even more if it is possible. What should be our best course of action to achieve that goal? Any input would be appreciated.
