Show articles on new page
Yes that would be relatively easy. How I would do that:

Edit the main menu: yoursite.com/admin/structure/menu/manage/main-menu and add menu item named My Articles (linking to a view is what I would do but you can choose to link it to anything you want - or nothing)

Edit the article content type: yoursite.com/admin/structure/types/manage/article


in Publishing Options deselect Promoted to Front Page
in Menu Settings:

check Main Menu under Available Menus
select My Articles (or whatever name you chose) in Default parent item



Then every time you create an article select provide a menu link. This will obviously work best for new sites where you don't have to go through and edit old articles to be in the menu.
