In ProfileInformation class file -

class ProfileInformation extends ActiveRecord
{
    $public $total_info;
    [....] //Rest of the code.

In Controller Action, change -

$criteria->select = array('t.user_Id,count(psh_profile_information_services.id) AS count');

to

$criteria->select = array('t.user_Id,count(psh_profile_information_services.id) AS total_info');

In view file -

foreach ($moli as $mol)
{
    echo "user_Id:  ".$mol->user_id." --- count:".$mol->total_info;
}

This should work fine.

If not, then just do simple debug -

echo "<pre>";

foreach($moli as $mol) {
    echo 'Total Info: ' . $mol->total_info . "<br />";
    foreach($mol as $key => $value) {
        echo $key . ' ' . $value . "<br />";
    }
    echo "<br />";
}

exit();

and check the values.
