metatags missing in translated homepages

How I can add meta tags on these 3 translated homepages? http://www.tec.lisam.it/lang-es.html - http://www.tec.lisam.it/lang-en.html - http://www.tec.lisam.it/lang-fr.html instead italian main homepage is ok: http://www.tec.lisam.it/lang-it.html I'm using joomla 1.5.14 with joomla sef patch 1.5.14 and joomfish, some people told me to check the template from admin, but I don't remember how to go there. I just have added the translated meta tags for the article in home page, but then we don't see them as now.
