Answer 1

$this->load->library('email');
$this->load->helper('path');
$this->load->helper('directory');
//setting path to attach files
$path = set_realpath('assets/your_folder/');
$file_names = directory_map($path);
$this->email->clear(TRUE);
$this->email->to($address);
$this->email->from('your#example.com');
$this->email->subject('Here is your info '.$name);
$this->email->message('Hi Here is the info you requested.');
foreach($file_names as $file_name)
{
$this->email->attach($file_name);
}
$this->email->send();

Answer 2

For multiple attachments you can use the same function multiple times,On your code you haven't used multiple times and not given loop too.
Try using the full path instead of just the url-
$this->email->attach('C:\Users\xyz\Desktop\images\abc.png');
or
$attched_file= $_SERVER["DOCUMENT_ROOT"]."/uploads/".$file_name;
$this->email->attach($attched_file);
also try changing the charset as-
$config['charset'] = 'iso-8859-1';
