Solution:

I got solution above my question.

Remove office_address and residential_address from config->form_validation.php

You can Validate office and residential address in controller, See below Code:

public function addMemberForm(){

$validation_error = array();

if(!$this->form_validation->run('add_form')){
    $validation_error[] = $this->form_validation->set_error_delimiters('<span style="color:red">','</span>');
}
elseif($this->input->post('mailing') == 'office'){
    $this->form_validation->set_rules('office_address','Office Address','required');
    if($this->form_validation->run() == false){
        $validation_error[] = $this->form_validation->set_error_delimiters('<span style="color:red">','</span>');
    }
}
elseif($this->input->post('mailing') == 'residential'){
    $this->form_validation->set_rules('resi_address','Residential Address','required');
    if($this->form_validation->run() == false){
        $validation_error[] = $this->form_validation->set_error_delimiters('<span style="color:red">','</span>');
    }
}


if(count($validation_error)){
    $this->load->view('admin_panel/add-member');
}
else{
    $this->session->set_flashdata('add_member_msg','<span class="alert alert-success">Member insert successfully</span>');
    return redirect('admin/add_member');    
}
}
