HTML code

<div id="replybutton" class="btn4 like" style="margin-top:-25px;margin-left:-10px;">
    <span class="btn reply" id="replyb">Reply</span> •&emsp;
</div>

<div class="col-lg-12" id="reply" style="background:#eff9c7;margin-left:50px;margin-top:-20px;display:none;" >
    <img  src="img/icons/no-icon-available.png" class="pull-left" style="   border-radius:50%;margin-bottom:3px;width:30px;height:30px;" />
    <p style="margin-top:18px;line-height:15px;"><strong class="font-1" style="margin-left:10px;">Hajime Sasota </strong> Sample comment<br>

<div class="btn4 disabled" style="margin-top:-25px;margin-left:-10px;">
    <span style="margin-left:5px;font-size:12px;color:gray;"><abbr class="timeago" title="">time</abbr></span>
</div>
</p>
<input type="text" class="form-control pull-right" style="width:88%;height:25px;margin-top:-10px;" placeholder="Write a reply..." />
</div>

JAVASCRIPT

<script type="text/javascript">
$(document).ready(function(){
$('#replybutton').click(function(){
$('#reply').toggle();
});
});
</script> 

Answer 1

id must be unique in a HTML Page, you should change id to class replybutton and reply and jquery code would be,

$(document).ready(function(){
    $('.replybutton').click(function(){
       $(this).next('.reply').toggle();
    });
});

Snippet,

 $(document).ready(function() { $('.replybutton').click(function() { $(this).next('.reply').toggle(); }); });
