FROM question q
INNER JOIN subject s ON s.sub_id = q.sub_id
INNER JOIN questionset qs ON qs.qset_id = q.qset_id
WHERE qs.qset_id =2 ORDER BY s.sub_id";

I am including some of your columns from question table here , you can add the rest same way
<?php
$con = mysqli_connect("localhost","root","","database_name");
$query1 = "SELECT q.q_id,q.setq_no, q.qtext_eng, s.sub_id, s.sub_name
FROM question q
INNER JOIN subject s ON s.sub_id = q.sub_id
INNER JOIN questionset qs ON qs.qset_id = q.qset_id
WHERE qs.qset_id =2 ORDER BY s.sub_id";
$presubID = 0;
<table class="table table-bordered">
while($row1 = mysqli_fetch_array($result1))
{
$subID = $row1['sub_id'];
if($subID != $presubID){
$subName = $row1['sub_name'];
<h2><?php echo "$subName" ?></h2>
$sno=0;
<thead>
<tr>
<th>Q.No</th>
<th>Q Set</th>
<th>Q text eng</th>
</tr>
</thead>
}
$presubID = $subID;
$sno++;
$qSet = $row1['setq_no'];
$qEng = $row1['qtext_eng'];
<tr>
<td><?php echo $sno; ?></td>
<td><?php echo $qSet; ?></td>
<td><?php echo $qEng; ?></td>
</tr>
<?php
}
?>
