I have to set up my New Living cum Dining room. Drawing is as attached. I do not have a sofa and I do not plan to buy any. Instead, I will prefer to buy some light weight chairs. I already have a 6 seater Dining table, a single bed and 3 old trunks of my MIL which I plan to put somewhere in this room and cover up with some padding above it and a good bed cover or Table cover. Please suggest me a good idea.

Love the armless sofa-bench! Try using it in the center as a "cross-linking" piece between the sofa and chairs. That way people can sit on both sides of it, conversing with the sofa people and the chair people. Put the chairs where it is and use the side table from the left of the pic, or the one with flowers, between them. You'll need one huge rug to anchor the space or two smaller, and very similar ones, to put on either side of the blue sofa-bench. The other two side tables are too tall and too short for your seating pieces, so ditch them. Use your coffee table between the sofa and armless sofa (18" away from each of them.) Here's a chart for judging table and lamp heights as you'll need to work on that for balance. Please try this arrangement, and post by commenting and using the Attach Images button to add pix of the update. We'll tweak it on out from there.

Which city r u in?

Greetings from Aura you have two options here go for indirect wall lights or wall lamps direct pendent lighting from slab point would also look good many ceiling lights options available suitable for no False Ceiling wall lights are always better it creates ambience.
