how can I create page/links and place it near "contact" and not to make it visible on the main menu?
I noticed the file "page.ftl" and I put a duplicate of "contact" that forwards me to other page. es: <li><a href="${url.context}/near_contact/near_contact.html">${msg('links.contact')}</a></li>
Notice: ${msg('links.contact')}
But now I want to understand all the around to create other link with other name, other template page etc. etc…and not display it in main menu
I'm not entirely sure I understand the question, but I think you're referring to changing the label of the new link you've created. If so, the localizable text properties are held in a properties file named "common.properties" in the "WEB-INF/classes/alfresco/messages" directory of the wcmqs webapp. In there, you'll find "links.contact", and you can add additional ones as needed.
Note that it would also be possible to use an asset collection to drive this kind of menu should you wish to.
