I change upload method with images[] according to @Denmark.

    private function upload_files($path, $title, $files)
    {
        $config = array(
            'upload_path'   => $path,
            'allowed_types' => 'jpg|gif|png',
            'overwrite'     => 1,                       
        );

        $this->load->library('upload', $config);

        $images = array();

        foreach ($files['name'] as $key => $image) {
            $_FILES['images[]']['name']= $files['name'][$key];
            $_FILES['images[]']['type']= $files['type'][$key];
            $_FILES['images[]']['tmp_name']= $files['tmp_name'][$key];
            $_FILES['images[]']['error']= $files['error'][$key];
            $_FILES['images[]']['size']= $files['size'][$key];

            $fileName = $title .'_'. $image;

            $images[] = $fileName;

            $config['file_name'] = $fileName;

            $this->upload->initialize($config);

            if ($this->upload->do_upload('images[]')) {
                $this->upload->data();
            } else {
                return false;
            }
        }

        return $images;
    }

You can upload any number of files

$config['upload_path'] = 'upload/Main_category_product/';
$path=$config['upload_path'];
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['max_size'] = '1024';
$config['max_width'] = '1920';
$config['max_height'] = '1280';
$this->load->library('upload', $config);

foreach ($_FILES as $key => $value) {

    if (!empty($value['tmp_name']) && $value['size'] > 0) {

        if (!$this->upload->do_upload($key)) {

            $errors = $this->upload->display_errors();
            flashMsg($errors);

        } else {
            // Code After Files Upload Success GOES HERE
        }
    }
}

And try using HTML like this:

<input type="file" name="file1" id="file_1" />
<input type="file" name="file2" id="file_2" />
<input type="file" name="file3" id="file_3" />
