Review my mutual funds

So I have started putting ₹5000 each on the following funds :

UTI NIFTY 50 INDEX FUND

UTI NIFTY NEXT 50 INDEX FUND

SBI NIFTY MIDCAP 150 INDEX FUND

SBI NIFTY SMALLCAP 250 INDEX FUND

please let me know if it is right or not considering I don't have much knowledge of mutual funds and this is what people around me advised.....
