Hello, if I understand correctly, you can do it this way.
With the method setInterval, you can repeat the desired commands after a certain time.
setInterval(function(){
$("#texto").fadeIn(ducarao).delay(tempo);
$("#texto").fadeOut(duracao);
}, tempo);
To select the DIV via Jquery you can use the selector $("#text"), thus selecting the element by its ID. Then with the fadein() function the "appearance" animation of the text is performed, also realize that it is possible to pass to the function the animation time. The delay() function to keep the text on the screen for 5 seconds and finally the fadeOut() function to make the text disappear.
I recommend that a researched in these functions on google, since I can not share the links of the same for not having enough reputation...
$(function(){
$("#texto").hide();
});
var i = 2;
setInterval(function(){
$("#texto").fadeIn(2000).delay(5000);
$("#texto").fadeOut(2000, function(){
$("#texto").html("<h2>TEXTO "+ i +"</h2>");
i++;
});
}, 2000);
<html>
<head>
<script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
</head>
<body>
<div id="texto" class="header_title">
<h2>TEXTO 1</h2>
</div>
</body>
</html>
Good luck!
