Yes, We can easily get the Name of the page, Excerpt of the page and Content of the page etc. by its id or by name.
Below easy and simple code will show you how it works..
Get page title, excerpt or content by id
$var_name = get_post('1'); // here 1 is id of the page.
echo $page_title = $var_name->post_title;
echo $page_excerpt = $var_name->post_excerpt;
echo $page_content = $var_name->post_content;
Get page title, excerpt or content by Name of the Page
$page_name = get_page_by_title( 'About' ); // here About is page name.
echo $page_title = $page_name->post_title;
echo $page_excerpt = $page_name->post_excerpt;
echo $page_content = $page_name->post_content;
