Answer 1

Anyways your question is too broad.
Here is step by step solution.
FRONTEND HTML + PHP
// TWO HARD DIV'S + THREE RANDOM ADS , BUT ONLY ONE OF THE AD GONNA TRIGGER.
<?php $random_number = rand(0,2); ?>
<?php ads($random_number,0); ?>
<div>your image or whatever</div>
<?php ads($random_number,1); ?>
<div>your image or whatever</div>
<?php ads($random_number,2); ?>
<?php $random_number = rand(0,2); ?>
<?php ads($random_number,0); ?>
<div>your image or whatever</div>
<?php ads($random_number,1); ?>
<div>your image or whatever</div>
<?php ads($random_number,2); ?>
COMPARISION FUNCTION
// Now create a function to compare if random number generated is equal to ad's placeholder.
function ads($rand_num, $placeholder){
if($rand_num == $placeholder){
echo "<div> YOUR ADS CONTENT </div>";
}
}
Note : It's not meant to run perfectly , it's just a outline on how to achieve that specific goal.

Answer 2

Do something like this (i tried to code it to be easy to understand):
<?php
function show_an_ad()
{
$the_ad = '';
switch (mt_rand(0,2))
{
case 0:
$the_ad = 'ad0.jpg';
break;
case 1:
$the_ad = 'ad1.jpg';
break;
case 2:
$the_ad = 'ad2.jpg';
break;
}
echo '<div class="col-md-3"><div class="hentry post1"><img src="'.$the_ad.'"></div></div>';
}
$ads_every_how_many_products = 3;
<div class="products-grids">
<div class="col-md-12">
<?php
$id=$_GET['id'];
$result1 = mysqli_query($con,"select * from products1 where sta='Active' order by id DESC LIMIT 0 , $resultsPerPage");
$counter = 1;
while($ro = mysqli_fetch_array($result1))
{
$nam1=substr($ro['pne'],0,60);
$url1=$ro['url'];
$description1=substr($ro['description'],0,200);
$price1=$ro['price'];
$price11=$ro['price1'];
$bid1=$ro['company'];
$image=$ro['image_name'];
$time=$ro['time'];
$tag=$ro['tag'];
?>
<div class="col-md-3">
<div class="hentry post1" id="post-225396">
Display Product in loop
</div>
</div>
<?php
if(!($counter%$ads_every_how_many_products))
{
show_an_ad();
}
$counter++;
}
mysqli_close($con);
?>
</div>
</div>
<div class="clearfix"> </div>
i don't have a php system here so there's a chance there could be a syntax error or something
