$("button").click(function(){
    $("p") .toggle();
});
});
</script>
 <?php 
    $bid=0;
    $bid=0;
    include 'model.php';
    $db=new database;
    $r=$db->msghead($admno);
    while($row= mysql_fetch_array($r))
    {
        $id=$row[0];
        $title=$row[1];
        $msg=$row[2];
        $date=$row[3];
        $sender=$row[4];
        $tit_status=$row["title_status"];
        $bid=$bid+1;
        $pid=$pid+1;
?>
<button style="width:80%;height:35px;" onclick="MessageDetailsById(<?php echo $id;?>)"   >


    <?php   
        if($tit_status=="1"){
    ?>      
        <i class="fa fa-plus-circle" aria-hidden="true" style="width:20px;float:left;"></i>  <i class="fa fa-envelope-open-o" aria-hidden="true"></i>&nbsp;<span id="active" class="sidebar-title" style="color:red;"><?php echo $title; ?></span> &nbsp;&nbsp;<?php echo $date;?>

What you want(toggle current and hide all at the same time) for that you have to change your structure and do like below:-

Example with your structure (you have to put your dynamic data carefully):-

$('.item p').hide();

$('.item button').click(function(e){
    
    e.preventDefault();
    var $this = $(this).parent().find('p');
    $(".item p").not($this).hide();
    $this.toggle();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="item"> <!-- this is needed otherwise not possible -->
    <button>Button</button> <p>span1</p> <br>
</div>

<div class="item">
<button>Button</button> <p>span2</p><br>
</div>
    
<div class="item">
<button>Button</button> <p>span3</p><br>
</div>
    
<div class="item">
<button>Button</button> <p>span4</p><br>
</div>

Try something like: 

<button ... data-id="<?php echo $id; ?>" ...>...</button>
<p ... data-id="<?php echo $id; ?>" ...>...</p>

And then On click do something like:

$('button').click(function(){
    $('p').find("[data-id='" + $(this).data('id') + "']").toggle();
});

I have not tested but I do use this case with dynamic elements in my programs.

you are assigning id to p

<p style="display:none;" id="<?php echo $id; ?>">

so just change your jquery code to this :

  function MessageDetailsById(id){
    $("button").click(function(){
      $("#"+id) .toggle();
    });
  }
