Wise parents, pls tell me which of these three Low cost diaper brands I should buy. I can't afford the price tags of MamyPoko etc. Anyone use onwards? What about petpet and FairPrice housebrand diapers?

I feel you have to try out all 3 brands on your LO to know which suits better. Get samples from online/friends. A suitable brand for others may not necessary be good for yours, likewise a suitable brand for your LO may not be suitable for others.
