Unfortunately, I don't really see much resale value in those domains - they don't seem to capture any commercial aspect that someone would be willing to pay a large premium to obtain rather than hand registering similar domains.
I think only keepMumbaiClean.com has real end user potential. I have heard about Indian cities' cleanliness issues and it could be used as a non-profit/campaign website. mid $xxx for that name.
as for alertmumbai.com, its brandable, so there needs to be that special entity that wants the name, or ur stuck with it.
mfgIndia.com is just OK. to say mfg means manufacturing is pushing it a bit. once again, it needs special demand to have end user appeal. very low $xx.
but at least they are .coms, so the foundation is good.
