How I install these extensions manually or why I can make for install this good.

Thanks.

I foound the problem, is that the ".xml" archives, are named ".xm_", change the extension of all the archives to .xml works fine, I don´t know why these archives are bad named

Because of Joomla looking for first xml file in archive and installs it. That's why we have mobilejoomla.xml for installation and other *.xm_ files for addons. During installation, that files are renamed to *.xml and then they are installed in a standard way.
