Hi Nupur -
I find this map to be helpful for the kind of information you seek, when used in combination with the information in the other replies.

I have used the search window to find the station by name. You can also search for hotels by name.
In the menus, under Points of Interest/ Gastronomy. I turned on all the options. Often, a restaurant may also be a hotel.
Under Points of Interest/Traffic, I turned on train and bus stops. Mouse over a train stop icon, and you will see the exact name of the station stop.
Also, Geneva has more than one main station. The one which serves connections to the south in France is not of concern, so, actually, Cornavin is the only name you need. It could also be called "Geneva main station" or "HBf" or Hauptbahnhof if you see it named in English or German.
In fact, in Zürich, although there is only one main station, there are 5 or 10 other named stations that are the remnants of terminals of older suburban rail lines, not unlike Paddington in London. In Zürich they all are connected to the main station, so, in effect,they are nothing more than enlarged stops along the train routes to the main station.
An example is Station Tiefenbrunnen (" deep fountain")_along the lake south and east of the main downtown area. Another, Station Zürich Wiedikon to the west of the main downtown area.
The extensive network of suburban railways still uses these stations, usually passing through temto Zürich main station.
The reason tha I mention this i sbecause you might see a possibly confusing list of "station" names in the timetable for Zürich.
For intercity travel, the main station is what you need in all of thse towns. . In Interlaken, Interlaken Ost is the main interface between the local mountain railways and the mainline intercity trains.
For travel within Zürich or its suburbs and some nearby towns, you can use trams, light rail, or regular trains on multi-stop suburban routes. So, the term station may be used to describe different kinds of train stops. Those suburban train lines may overlap with intercity trains on some routes.
The timetable linked by Lucas in Item #2 can help you understand the options.
