Answer 1

I assume you're talking about Admin users when you mention user role

This code should tell you the admins role

$admin_user_session = Mage::getSingleton('admin/session');
$adminuserId = $admin_user_session->getUser()->getUserID();
$role = Mage::getModel('admin/user')->load($adminuserId)->getRole()->getData();

I'd wrap it in an IF to make sure they're logged in before firing it, something like

if($admin_user_session){
    switch ($role) {
        case 'Don1':
            // Do something for Don 1
            break;
        case 'Don2':
            // Do something for Don 2
            break;
        case 'Don3':
            // Do something for Don 3
            break;
    }
}

Answer 2

$cursession = Mage::getSingleton('admin/session');
$userId = $cursession->getUser()->getUserId();
$role = Mage::getModel('admin/user')->load($userId)->getRole()->getData();

You can get role regarding data in the $role array. By using that, You can show your desired message.

To get logged in user in admin-end.

    $admin = Mage::getSingleton('admin/session')->getUser();
    if ($admin->getId()){
        echo $admin->getUsername();
    }

To get logged in user role

$role_data = Mage::getModel('admin/user')->load($admin->getId())->getRole()->getData();

To get logged in user in front-end.

$customerSession = Mage::getSingleton('customer/session');
if($customerSession->isLoggedIn()) {
     $customerData = $customerSession->getCustomer();
     echo $customerData->getId();
 }
