From the looks of what you need I think the Logan will be a sensible choice. Since you have not mentioned your choice of fuel, I would assume you are ok with either. Therefore a Logan 1.5 DLE should be VFM for you giving you ample space for yourself (and 4 others). You also get A/c and power steering but no other frills. I have checked out the prices in Cochin and find the DLE costing 6.17 on road. And remember, a diesel will have a better resale.
Having sat in one I can vouch for the space and comfort element. Cannot comment on the performance and maintenance issues yet.
