Do you have any photos you can share? We do better with both floor plan and pix. I think the 9' area should be devoted to a library/reading nook with bookcases on the two walls and a comfy chair and floor lamp for reading. I see lots of doors but no windows in your space. The stretch of space from the entry to the balcony/gallery should be kept open for traffic flow, so Place the FP on the 7.5' wall to be seen upon entering. I think 'd try a sectional with two equal wings. Put the TV on the 7' wall between the two doors and float the sofa so one wing faces the FP and the other the TV. Use a credenza 25% wider than the TV rather than a TV stand. In the jog that has a 6' and a 4' wall, try a family game or chess table and stools. Be sure to get a big coffee table made of reclaimed wood so people can put their feet up on it.

Hi Good Morning! Location is Goa, well I don't have a revised, request the builder to provide me one. The north is towards the master bedroom, balconies to the east are still part of the plan whereas smaller balconies to the west ones have been integrated with the kitchen and master bedroom resp. Well, Mr. Nitin not open to any kind of civil work, open to flexible ideas in decorating my living room eg prayer space with room divider or so.. Thanks Shivam

A typical partition or anything on the floor may make the space look constrained. I'd suggest you just use a different finish of flooring to partition the space...for e.g. you can have wooden flooring installed on top of the tiles in the area where the sofa is kept - to the human eye this will both partition the space as well as maintain the spaciousness.
