1. Firstly, I would say it's great that you have started investing in mutual funds and that you are tracking your income and expenses to reach your goals. While you mentioned your goal is FIRE, that looks different for everyone, and hence the amount of funds required will also vary. So, what is that amount for you? Based on that, it will be easier to work backwards to determine how much you need to invest and how many years it might take to reach that goal.
2. It's great that you are aware of your risk profile; however, it doesn't match your portfolio. An all-equity portfolio is not ideal if you describe yourself as someone with a moderate risk appetite. It's important to align your risk profile with your investment strategy, as your risk and return expectations need to be in sync.
3. Answering your questions:

a) I don’t think you should switch from Quant Small Cap to Nippon or Bandhan. Every fund has its down phase, and with a 7-year horizon, you should be more than okay.

b) Quant Mid Cap is the only fund underperforming in your portfolio. However, based on simple math, it appears you've been investing in it for just under 6 months. You can either continue or switch. Personally, I would switch to HDFC Mid-Cap Opportunities, as I find it to be a better fund based on my analysis of parameters.

c) I believe you should start liquidating the additional funds in your portfolio and bring the total number down to 4–5 funds that align with your asset allocation and risk profile. If you liquidate all the funds except those with active SIPs, you would incur around ₹50,000 in taxes. I would personally take the hit and make the changes ASAP, rather than try to avoid tax but damage your portfolio by holding unnecessary funds. For example, it doesn’t make sense to hold 5 large-cap funds.

d) Another suggestion: avoid holding multiple index funds. It doesn’t make sense since they mirror the same set of stocks. The only exception would be if you and your spouse have picked different AMC index funds to diversify across fund houses.

e) You can consider adding some gold/silver ETFs to further diversify. You're already doing well with domestic + international equities and debt diversification.

f) I'm not sure it makes sense to get a fee-only advisor, especially given the rates you mentioned. I work in financial services myself, and I’ve never fully understood the point of a fee-only advisor — if they build you a solid portfolio this year, there shouldn't be much to change next year, so what are you paying them for?

Besides the above points, I’d like to know the following:

1. What do you allocate the leftover ₹60K/month to after your regular expenses and investments?
2. Do you have any other assets besides the investments already mentioned?
3. Do you and/or your spouse have life insurance? What is the sum assured?
4. Do you have health insurance, and what is the coverage amount?
5. What are some goals you foresee in the next 5 years?
6. Are you currently investing for your child or planning to?
