Parents are not convinced for a health insurance

21F, just graduated and got an average pay job of 4.2 LPA. Currently saving for CFA for november attempt because i want to work in finance and get a good pay. Recently I came to know that my parents does not have any life insurance plans or any medical insurance for themselves or for me and my younger brother. Idk how and when they enrolled in a LIC policy which is like pension scheme, where they give some amount every 6 months for probably 10-15 years and then the policy will give them returns after the maturity period and it also covers accidental, natural death or disability. I tried to convince them for an actual life insurance and health insurance policy but they just dont care enough. In fact they are trying to get me into such “pension policy”. I know if i start an SIP i will get way better returns than these policies. So now i have decided that i will get a life insurance policy and health insurance for them and for me and brother under floater insurance plans. I also want to get an life insurance for me too but my salary seems to be not enough at this point to do all this. I have to take 1 lac from a relative so than i can pay registration fee for the cfa. This means that i will also have to pay them back as soon as possible. Im planning to give 90% of my salary per month to get over this 1 lac debt. I have around 40k saved, it will take next 3-4 months to pay them back. I want to get insurance policy for them asap but im not quite sure how do i do this. Im really worried because my parents have no emergency funds, no savings for future at all. I want to create emergency funds but dont know how. Then i have my younger brother, he will also go in college in coming 2 years, i’ll have to pay his fee. I dont know how to save and where to start. Is it really necessary to get a life insurance for them? Please help me to understand how can i prioritise my limited funds, feel free to guide me.
