I do not want to use wp_head(); because it also generates other scripts, styles and whatever plugin or code you have in your wordpress website.

. I only want to get the Yoast SEO generated code as shown above.

Answer 1

get_post_meta(), use this to get the meta yoast in the page 

echo get_post_meta(get_the_ID(), '_yoast_wpseo_metadesc', true); 
echo get_post_meta(get_the_ID(), '_yoast_wpseo_title', true);  

and you this code to get the meta values to get the values related to each page just check the  post meta tables
