<?php
          global $row6;
          $query= "select s.name ,s1.price from services s ,seller_services s1 where s1.service_id = s.id;";
          $result= mysqli_query($conn3,$query) or die(mysqli_error($conn3));
          while($row6=mysqli_fetch_array($result))
          {
            ?>
          <div class="col-md-3 col-sm-4">
            <div class="pro-box">

PHP

$query5= "Select *from services where id = '$id'; ";

Not a solution to your question, but another problem you have.
Never build an SQL query by concatenating strings. Sooner or later, you will do it with user inputs, and this opens door to a vulnerability named "SQL injection", it is dangerous for your database and error prone.
A single quote in a name and your program crash. If a user input a name like "Brian O'Conner" can crash your app, it is an SQL injection vulnerability, and the crash is the least of the problems, a malicious user input and it is promoted to SQL commands with all credentials.

You should check your query spacing (for a start). You have

PHP

select *from 
instead of
select * from

Using 'u' instead of 'you' and other such cell-phone-texting junk is a sure way to develop sloppy habits. It's OK for error in English - it is not your first language. I am not referring to language errors, but deliberate junk. Computers are very rough on coders with sloppy habits. "Almost doesn't count".
