Your issue is caused by un-unique ids. You have $stmtAuction->rowCount() number of id='countdown'. ids are supposed to be unique. So javascript/jQuery will only find the 1st/unique id='countdown'. You need to use class='countdown' instead -

<?php
    $stmtAuction = $db->prepare("SELECT * FROM auction WHERE expired_at >= CURDATE() AND status = 'available' ORDER BY expired_at ASC");
    $stmtAuction->execute();
    if ($stmtAuction->rowCount() > 0) {
        while ($item = $stmtAuction->fetch()) {
        ?>
            <span class='countdown' value='<?php echo $item['expired_at'];?>'></span>
                  ^^^^^-change from id to class
<?php
        }
    }
    ?>

Now in your javascript, you need to use the class selector - $(".countdown") - and loop over each class using $.each().

<script>
    $('.countdown').each(function(){
        $(this).countdown($(this).attr('value'), function(event) {
            $(this).text(
                event.strftime('%D days %H:%M:%S')
            );
        });
    });
</script>
