Is it possible to put an artificial satellite into an orbit in such a way that it will always remain direct over a city (I mean at any specific place)?

Hello Sagar,

The kind of orbits you are referring to are called Geostationary.  They are possible only if the city in question lies directly on the equator.   A nice discussion of them can be found here:
