Accessing loop functions (e.g the_title or the_content) from post ID

You can make use of get_post to get the post objects of a given post.

This will be unfiltered objects, so you would want to make use of apply_filters and the appropriate filters described in the linked page.

If you need to get info from a custom field, whether native custom fields of ACF fields, you can simply add the ID to the get_post_meta for native custom fields or the_field or get_field functions in ACF.

Remember, by default, the post ID of the current post is used, but you can change this to any post ID you wish to get info from
