If you are returning images from image fields as image opbjects then the basic meta data is included in that object. If you are returning IDs then you can use wp_get_attachment_metadata(). If you are returning the image URL then I don’t think it can be done.
To get the content added to ACF fields attached to the attachment you would use
get_field('field_name', $attachment_id)
I don’t know if the $attachment ID is returned as part of an image object, you may need to return IDs to get them.
