Raj,
     First, define for yourself some global variable to hold a pointer 
to the popup windows you will be generating:
var ptr1 = null;
var ptr2 = null;
var ptr3 = null;
     Then, in one or more functions you can generate your popup 
windows and save a pointer to that window:
ptr1 = window.open(...);
ptr2 = window.open(...);
ptr3 = window.open(...);
     Lastly, you can have other events which will determine upon which 
window to focus:
if (ptr1 && !ptr1.closed) ptr1.focus();
if (ptr2 && !ptr2.closed) ptr2.focus();
if (ptr3 && !ptr3.closed) ptr3.focus();
     Note that these same pointer variables can be used to reference 
the document inside of that particular window.  The following is an 
example which would reference the value of a text box within a form in 
a popup window -- providing the correct indices are supplied to the 
collections shown:
var ele = ptr1.document.forms[x].elements[x];
alert('Field "'+ ele.name +'" has a value of "'+ ele.value +'".');
Take care,
