id should be unique use class instead. You can use next() to select element immediately after clicked element

$(document).ready(function() {
  $(".post-vote-top").click(function() {
    $(this).next(".post-vote-middle").text(function(i, v) {
      return parseInt(v, 10)+1;
    });
  });
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<table>
  <tr>
    <td id='post-nomor'>$no.</td>
    <td id='post-vote' align='center'>
      <div class='main'>
        <div class='post-vote-top'>up</div>
        <div class='post-vote-middle'>1</div>
        <div class='post-vote-bottom'></div>
      </div>
    </td>
    <td></td>
  </tr>
  <tr>
    <td id='post-nomor'>$no.</td>
    <td id='post-vote' align='center'>
      <div class='main'>
        <div class='post-vote-top'>up</div>
        <div class='post-vote-middle'>1</div>
        <div class='post-vote-bottom'></div>
      </div>
    </td>
    <td></td>
  </tr>
</table>
