I haven't used TCPDF I use mPDF but the logic is pretty much the same. The following statement stores the pdf file in the directory

$pdf->Output($applicantname.'_'.$applicantid.'.pdf', 'I');

You can loop through you applications to create list of PDF files like

// Assuming you have $applications as array of applicants
foreach($applications as $application)
{
  // All PDF settings goes here
  $pdf->Output($application['name'].'_'.$application['id'].'.pdf', 'I');  
}

Then follow Creating .zip file : PHP thread to create an archive and then redirect to that archived file path which will download it.
