Since you want IE8, IE10 and IE11 to maintain their normal behavior, I believe the best thing to do is to place a conditional on IE9
<!--[if IE 9]>
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8">
<![endif]-->
Remembering that you can add conditions to check the IE version up to IE9.
From IE10 this check is ignored (as well as the contents).
EXTRA:
sometimes I want to add the following code snippet:
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<!--[if IE]>
<script type="text/javascript">
alert('Para continuar atualize o seu IE!');
window.location.href = 'http://windows.microsoft.com/pt-br/internet-explorer/download-ie';
</script>
<![endif]-->
@rray I think he wants to know if you can give the user a page (created by you) when opening the page http://www.meusite.com if you can always emulate IE8 for example.

I want to emulate depending on what ie is using
