I have number of City locations which collected from Google Earth. They are in WGS coordinate system. I need to convert them  into UTM coordinate system,separably. Is there any procedure to find respective UTM  zone for each city/ place in ArcGIS?

Step 1

1 .Navigate to the following location using catalog window / ArcCatalog

C:\Program Files (x86)\ArcGIS\Desktop10.2\Reference Systems

2. In a new arcmap session add "utm.shp" from the above location

3. Add your location layer ( which is in WGS)

4. Use Identify tool and click on the city

5. You will find zone in the identify window

Step 2

To reproject the data from WGS to UTM you can use Project tool (Data management).

ArcGIS Help (10.2, 10.2.1, and 10.2.2)

Hope this is helpful

Just a picky terminology issue....

You can't actually have your data IN WGS84. Because WGS84, by itself, is not a coordinate system.

It is a datum & ellipsoid (& a geoid).

You can have it IN GCS_WGS84 (geographic, based ON the WGS84 datum / ellipsoid).

Then project it to a projected UTM zone based on the WGS84 datum.

An algorithmic way to determine the UTM zone is here and reproduced below. I originally cribbed it from Chuck Gantz.

ZoneNumber = floor((LongTemp + 180)/6) + 1;

if( Lat >= 56.0 && Lat < 64.0 && LongTemp >= 3.0 && LongTemp < 12.0 )
   
ZoneNumber = 32;
endif
// Special zones for Svalbard
if( Lat >= 72.0 && Lat < 84.0 )
 
if  ( LongTemp >= 0.0  && LongTemp <  9.0 )
   
ZoneNumber = 31;
  elseif
( LongTemp >= 9.0  && LongTemp < 21.0 )
   
ZoneNumber = 33;
  elseif
(LongTemp >= 21.0 && LongTemp < 33.0 )
   
ZoneNumber = 35;
  elseif
(LongTemp >= 33.0 && LongTemp < 42.0 )
   
ZoneNumber = 37;
  endif
endif

(I'm sure there are similar posts on GeoNet, but this is the first one returned by Google.)
