Answer 1

Controller
public function get_names(){
$this->load->model('model_name'); //If not loaded in the autoload.php file
$names = $this->model_name->all_names();
$this->load->view('view_file_name', compact('names'));
}
The query in the model will be like this
public function all_names(){
$this->db->select('name');
$this->db->from('users');
$this->db->join('messages', 'users.id = messages.sender_id');
return $this->db->get()->result();
}
To join with recipient_id do like this
$this->db->join('messages', 'users.id = messages.recipient_id');
Then use foreach loop to show all names in the view
foreach($names as $row){
echo $row->name;
}

Answer 2

model
$this->db->select('messages.*,u1.{name of field for username} as sender_name,u2.{name of field for username} as recipient_name');
$this->db->from('messages');
$this->db->join('users u1', ' u1.id = messages.sender_id', 'left');
$this->db->join('users u2', ' u2.id = messages.recipient_id', 'left');
$q2 = $this->db->get();
return $q2->result();
View
<?php foreach ($get_pesan as $pesan) { ?>
<strong> Sender : <?php echo $pesan->sender_name; ?> </strong>
<strong> Recipient : <?php echo $pesan->recipient_name; ?> </strong>
<a> <?php echo $pesan->body ; ?></a>
<?php } ?>
i have forgotten you cannot join one tale more than one time you need to use table aliases. it will work for you/ just place the name what ever fild name is in your data base.
it will work or else share me screen short of your table and error pages
