I think they mean 5 rooms, not 5 bedrooms.....one master bedroom and 2 bedrooms for children with twin beds or bunk beds in each. I lived in a 1,300 sq ft house for 2 yrs with my husband and 2 sons. My suggestion would be to have an open floor plan for the kitchen, dining area and family room in one large room. Add a bar in the kitchen for casual dining. Be sure to include storage in family room for toys, games, etc. Add a built in desk in eiher the kitchen or family room areas . The master bedroom and bath should be large enough to accomodate a queen size bed and if possible a sitting area (maybe a bay window large enough for for a small loveseat or a couple of comfortable chairs). I would recommend a large walkin shower but no tub for the master bath. Instead have a nice size tub/ shower combo in the hall bath. Too make your house feel larger, use neutral camel, beige, gold or grey paint and carpet through out the kitchen, dining area, family, hallways and hallbath. If you want to add color, limit it to 3 bedrooms. Hanging all your window treatments at ceiling height will make your rooms feel larger and taller.

Mohammad. I understand your program. You may be lost in the details at the moment. Please do follow and trust the advice given here by all these people. You are about to embark on a reasonably expensive journey. Get professional help with someone who you can sit down at a table and brainstorm with them your ideas and intentions. There are Architects and there are professional building designers who are members of the American Institute of Building Design (AIBD) who are well versed in projects such as yours. I personally love a design challenge. After 38 years designing homes and special use buildings I enjoy this type of challenge the most. I am in Ohio and may not be close to where you are but I am sure with a little investigation you will find the best design professional for you.

Best to consult an architect as I have said. Plot is a bit small to fit all your requirements in a single floor.

The kitchen sink should go towards the corner next to the stove area since the plumbing would be easier due to the bathroom pipeline on that wall. The stove should be moved from there to the basin area but more central. I couldn't zoom in but what is loft above. Anyway, I think you could get rid of that wall and make it a half wall, and include a counter with 2 -3 bar chairs like for quick meals. Puja area, I think would be better elsewhere since there is non-veg food and sometimes alcohol consumption. You could have more like a partition shelf wall between dining and living, need to think more on moving the puja area somewhere else. Also, since the common bathroom is right there, you would not need another basin next to the dining area, its just not a good sight . You could mail me the floor plan and we could work on it more elaborately, but this is simply a skimmed review of the layout. Hope I was helpful .
