Answer 1

Your models start with
class Company extends CI_Controller {
They should be
class Company extends CI_Model {
Try changing
$this->load->model('Product');
$this->load->model('Company');
to
$this->load->model('product');
$this->load->model('company');
notice the lower case model names. Just tried it here and got the same error as you.

Answer 2

$models = array(
'menu_model' => 'mmodel',
'user_model' => 'umodel',
'admin_model' => 'amodel',
);
foreach ($models as $file => $object_name)
{
$this->load->model($file, $object_name);
}

Answer 3

Try giving a name to you model :
$this->load->model('Company', 'Company');
