you can use function the_author(); in loop.
thie function display the author name by post-id parameter. but you should put it in a loop.

Figured it out.

In case nayone needs it:

<?php
$post_id2 = get_post_meta($post->ID, 'bottom_img_excerpt1', true);
$queried_post = get_post($post_id2);
$author_id = $queried_post->post_author;
$user_info = get_userdata($author_id);
$first_name = $user_info->first_name;
$last_name = $user_info->last_name;
echo get_avatar($author_id);
$title = $queried_post->post_title;
echo '<strong>' . $title . '</strong> <br />';
echo "$first_name $last_name";
?>
