<a name="something">, instead use <a href="#div_id"> in combination with </a> <div id="div_id">foo</div>.
for all of these tags:
use css to style a div or span instead of these tags.
<marquee> too got replaced by css, you can set the overflow-style option to marquee.
<acronym> is deprecated too, i guess you may use <abbr> instead.
<applet> was already deprecated in HTML4 use <object instead>.
<bgsound> is no more in HTML5, too. Use the <audio> tag instead.
<dir> also isn't available since HTML4, if you want to display a directory listing use the <ul> <li> list tags.
<frame>, <noframes> and <frameset> are gone for good, but you may still use iframe or maybe in some situations you could load content via AJAX and inject it in your DOM.
<isindex> already deprecated since HTML4.
<tt> which stands for teletype text, it is used to render text using a monospaced font.
