It looks like a small room to me. I cant suggest a placement plan with knowing the plan. But some tips I guess may work for the corner. 1 . Use no temple. 2, use Dias and Mirror 90' Degree on the walls. to reflect idol in the mirror. 3, Many small one medium size Idol is better than too large one or two many small ones. 4. Use glass temple . 5. Make hanging temple if cant change the corner. 5. Don't use anything over and under as storage.

I can see a dresser area outside the bathroom in the floor plan and a separate wardrobe area as well. You can make an exclusive wardrobe and dresser area for your daughter just outside the bathroom. The wardrobe space can accomadate a long study table with wall mount bookshelf and a mix of open and closed storage. On the same wall you can make a sleek wardrobe for your son. Trundle beds are also quite in these days, you can place a trundle instead of a regular bed. Place the bed against the same wall as shown in the floor plan but tucked away in the corner. On the opposite wall you can get a nice kid friendly theme on the wall and create a small seating. Use all white furniture and add pops of colour through curtains and bedding

Can anyone please suggest a company name, I am looking for gold color tiles for my swimming pool in Delhi ?

I feel partitions are not needed. You already have too much for the space. Adding a partition will shrink the space further. The simplistic solution, you do not wish to discard any furniture would be to paint all the walls in lighter pastles. And use some wall painting frames to highlight certain walls.
