I'd say that you could probably get $50-$100 for winmobile.in, $200-300 for indiahacks.com and hackindia.com, and maybe $150 for incric.com. I might be a little off, but those prices seem fair to me. Good luck selling them!
First one is a bit okayish but rest are good. I am sure you would fetch good money for rest of the three. Generally price depends in willingness of buyers so I wouldn't particularly hint towards a fix price but you can definitely hope for what MICE has posted!
