Answer 1

First you should switch to the popup and then try to find the element.
You can use following code snippet

String parentWindow = driver.getWindowHandle();
Set<String> windowHandles = driver.getWindowHandles();
Iterator<String> iterator = windowHandles.iterator();
while (iterator.hasNext()) {
   String handle = iterator.next();
   if (!handle.contains(parentWindow)) {
                    // Switch to popup 
                    driver.switchTo().window(handle);
                    // Add code to find element 
       }
}
// Switch back to original window
driver.switchTo().window(parentWindow);

This code will work with any number of popups
