Xperia Ion. After recent price cut, its actually a good buy. Still costlier by 1K than specified budget.
L7 II if dual SIM is required.
Can not comment on Galaxy
Grand but user reviews aren't good.
Lumia 720 is actually a best VFM product if only your friend is not a power user and is ok some of the limitations of OS. Otherwise, for an average joe, it's actually better than droids in similar price range.
