Answer 1

Change your support field to this 'supports' => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' ) );

Answer 2

I hope you have created the custom post type by adding the function register_post_type() in theme function.php file. If yes, you just update your code with 'supports'. Then go to Screen Options and click 'Excerpt'.

$args = array(
    'supports'           => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' )
);

register_post_type( 'book', $args );

Or you can also add the following code

add_action( 'init', 'my_add_excerpts_to_pages' );
function my_add_excerpts_to_pages() {
     add_post_type_support( 'page', 'excerpt' ); //change page with your post type slug.
}
