stock suggestion

So , I've applied for 3 IPO's but got none. so Now I have 40k fund for investment(not a big amount). should I invest in those IPO on listing date for long term? (Inventurus, VMM , mobikwik). or should I invest in stocks? I have Suzlon , jindal stainless in my portfolio along with 3 MF (parag parikh flexi, ICICI prudential nifty 50 /ETF , motilal oswal midcap) I'm analysing Nalco (good financials and currently at best price I guess) and vedanta since quite some time. should I buy one of this? or should just add this fund into my mf portfolio or buy IPO on listing date? or should I just apply for another IPO (four IPOs are on the way). I'm more confused that's why.. I'd like honest suggestions from fellow redditors :) also. I'm from lower middle class so this is my savings which I want to invest for long term.
