Need advice on how to plan finances and investements as I just started my first job.

I am 23 years old and started my job 4 months ago, I get 1L/month in hand, by this month end I will have 6L amount in total. I just have a 1L loan I need to repay (this is my first priority), there's no interest on this. I have almost no expenses every month as my job give me accomodation, food and all utilities. I have some subscriptions and few miscellaneous expenses which are not even 20% of my salary. So for the next 1 year I am not spending more than 20-30% of my salary per month.

Now I want to plan and learn everything from investemnets, savings, emergency funds, budgeting; basically everything to do with money. How do I go about it, where do I learn things and what all aspects I have to take care of?

I have 1 credit card, have a demat account which I have used to do some small investment of 20-30k few months ago and my savings account. I have term life insurance of 2 CR and health insurance too.
