I am thinking of covering the window panes with 5 fold newspapers.
What other inexpensive items/materials can be used to cover the window panes for keeping the house cool from inside?

I see you're writing from India, so the standard US answer of installing light blocking cellular blinds may not apply to you.
Consider using a thin material that reflects light instead of absorbing much of it, such as aluminum foil. If you want it to look nice, you can stack the foil between a light piece of paper for the outside (so the neighbors aren't blinded by the reflection) and cardboard (for rigidity).
I'm not sure that this would be available to you locally, but this is what I use on my bedroom. Cuts easy and has a reflective side and is very cheap. Works well enough to keep the Florida heat out of 50 year old leaky windows.
