          TopPosition=(screen.height)?Math.floor(Math.random()*((screen.height-h)-75)):100;
     if(pos=="center"){
          LeftPosition=(screen.width)?(screen.width-w)/2:100;
          TopPosition=(screen.height)?(screen.height-h)/2:100;
     }else if((pos!="center" && pos!="random") || pos==null){

"I made a javascript function, but it only open one window pop up"
If you use the same name then the browser will not open a new window but just re-use the previously opened window. You will either have to not use a name or use a different name for each pop up.
To get the new window to be on top get the handle to the new window and assign it the focus
var win = window.open(mypage,myname,settings);
win.focus();
