A (stupid) doubt: Is it same as Mis-Aligned Dies?

Questions aren't stupid. No. It's not the same. In a modern coin press, the dies should cover the whole flan on both sides, so they would be equally large in diameter and their centers would be perfectly aligned. Normally, at least on of the dies is mounted on a central shaft. If something goes wrong in the press, the shaft may bend and the two die centers will no longer be perfectly aligned. The result is a "new moon" of blank metal on both sides. See illustration.

Aditya,
  Both the 2007 steel & 2009 brass 5 Rupees that you sent me earlier this year have misaligned dies.I do collect Indian error coins as well as the 'normal' coins.

Aidan,
Are they mis-alligned or rotated axis? It is not so frerquent to come across misalligned dies but these days rotated die strikes are quite frequent. If it is indeed mis alligned, I would like you to upload a picture of atleast the Rs 5 Al-Br coin as I am curious to see such an error. I have quite a few error coins including misalligned strikes (what we refer to as shifted blank), but have yet to come across a Rs 5 Al-Br issue. I will check up the Rs 5 & Rs 10 coins that I have for die rotation error after I return back from my current trip.

Amit,
  I am still unable to do any photos,as I haven't yet bought a replacement copy of PhotoStudio 5.5 to replace the one I can't find.

Rotated dies on coins are misalignments,as they are not the normal arrangement of the dies in the coining press.

Aidan,
I agree that both are errors. However as I said above, one is more common than the other. A layman will be able to pick up a mis alligned strike but die axis rotation is seen only if you are looking out for it. Also for this see http://www.worldofcoins.eu/forum/index.php/topic,3693.0.html

I had posted picture of a 2007 5 rupee error coin found in circulation here.

Nice error coin MS. The coin clearly shows that the blank shifted during the punching process.
