$exp_date=$this->input->post('expense_date');
$expense_ids= $this->input->post('expense');
$expense_ids=substr($expense_ids,0,strlen($expense_ids)-1);
$expense_id_array = explode(',',$expense_ids);
$id=$this->session->userdata('userid');
for($i=0;$i<count($expense_id_array);$i++)
{
$required_id = TRIM($expense_id_array[$i]);
$this->form_validation->set_error_delimiters('<div style="color:#B94A48">', '</div>');
$this->form_validation->set_rules('exp_amount_'.$required_id, 'Expense Amount', 'required|numeric');
$this->form_validation->set_rules('comment_'.$required_id, 'Comments', 'required|alpha');
if ( $this -> form_validation -> run() === FALSE )
{
$this->index();

Answer 1

As the OP Wants to show the all the Errors inside a div
<div id="error">
<?php echo validation_errors(); ?>
</div>
As the OP Wants some additional info,
To include a view or common page
$this->load->view('yourownpage');
Then you should have yourownpage.php inside your views folder
To have pagination, Have this in your controller's function
$this->load->library('pagination');
$config['base_url'] = 'yourownpage';
$config['total_rows'] = 200;
$config['per_page'] = 20;
$this->pagination->initialize($config);
echo $this->pagination->create_links();
Note :
Make sure to place the error div in the place that didn't hurt your textbox
