Try:

var str = "My Name is @parm1 and My father Name is @parm2 and also my nick name is @parm1 and i live in @parm3";
var values = "James,Nortain,TEST Address".split(",");
var result = str.replace(/@parm(\d+)/gi, function(a,b){
    return values[b-1] || a
});

document.write(result)

This will replace each of the name separated by , using for:

var str = 'My Name is @parm1 and My father Name is @parm2 and also my nick name is @parm1 and i live in @parm3';

var strName = 'James,Nortain,TEST Address';

var names = strName.split(',');

for (var i = 0; i < names.length; i++) {
    str = str.replace('@parm' + (i + 1), names[i]);
}

alert(str);

Yeah - that's better. Also more correct than the other answer posted, as the OP's example result didn't replace the second @parm1 value (whether that's intentional or not...?!)
