If you're using eZ publish 3.6 or newer, I would suggest to use foreach instead of section (it is deprecated). You will find examples of how to use foreach in the technical manual: http://ez.no/doc/ez_publish/technical_manual/3_7/reference/template_control_structures/looping/foreach
The technical manual also contains more information on accessing array elements: http://ez.no/doc/ez_publish/technical_manual/3_7/templates/the_template_language/variable_usage (search for "index lookup")
