Just append i and increment it till your while loop goes on..

<?php
    $i=1;
    while($fet=mysql_fetch_assoc($sql1))
    {
       echo '
        <tr>
        <td>
          <input type="text" id="hello'.$i.'" name="hello'.$i.'" data-id="'.$fet['username'].'" onchange="loadXMLDoc(this.value,'.$i.')" value='.$fet['username'].' >
</td>           
       </tr>';
       here write ur code for other fields

         $i++;
    }
 ?>

<script> 
function loadXMLDoc(a,i) 
{ var d= document.getElementById("hello"+i).value; } 
</script>

Don't use foreach as bellow way.

foreach($sql1 as $value){

// don't generate html here

}

Because it may brake the html

Use foreach bellow way.

<?php

foreach($sql1 as $value):

?>

<tr>
 <td><input type=text id='hello' name='hello' data-id="<?php echo  $value['username']?>"    onchange='loadXMLDoc(this);' value=<?php echo $value['username']?>>
   <td><input type=text id='uid' name='uid' onchange='loadXMLDoc(this).' value=<?php echo  $value['id']?>>
</tr>

<?php endforeach() ?>
