It may seem to be harder to add postmeta if one meta box deals with add_post_meta and another meta box deals with update_post_meta because it does not support good practice. In having multiple posts in one meta and single post meta in another, using json to store data in one field would be easier. Manipulating the json data is also easier rather than dealing with add_post_meta and update_post_meta if this is the case.

You also give delete_post_meta a key but take a careful look at the answer. delete_post_meta will delete the entire key. That is why I said delete_post_meta will not work. You need to pull the data, process it in PHP and then put the data back.

If you're going to send the whole $post->ID and it will get the array of records, how can I detect the specific meta_key set to be deleted?

Your description makes me think delete_post_meta won't work, but the short answer to that question is that you have to give the post ID to the function.
