    $users = DB::table('activationFee')->orderBy('id', 'desc')->get();
    foreach ($users as $row) {   
        $users = DB::table('users')->where('id', $row->sender_id)->first();

I Think this code will help you i dont know the username field is exiest in which table so i will give the both options : may b this will works for you :

function GetactivationReq() 
{
  $settings = DB::table('settings')->where('id', 1)->first();    
  $users = DB::table('activationFee')->orderBy('id', 'desc')->get();
  foreach ($users as $row) {   
  $users_new   = DB::table('users')->where('id', $row->sender_id)->first();
  $receiver = DB::table('users')->where('id', $row->receiver_id)->first();
  $user = DB::table('userdetails')->where('userid', $row->sender_id)->first();
echo '<tr>
    <th><input type="checkbox" class="select-all" value="1"></th>
    <td>'.@$users->username.'</td>
    <td>'.@$users_new->username.'</td>
    <td>'.$user->accountname.'</td>
     <td>'.$receiver->username.'</td>
    <td>'.$settings->currency.''.$row->amount.'</td>
    <td>'.$row->payment_status.'</td>';
    }
}

The code makes no sense but maybe this one can help:

function GetactivationReq()
{
    $settings = DB::table('settings')->where('id', 1)->first();
    $activationFees = DB::table('activationFee')->orderBy('id', 'desc')->get();
    foreach ($activationFees as $row) {
        $user = DB::table('users')->where('id', $row->sender_id)->first();
        $receiver = DB::table('users')->where('id', $row->receiver_id)->first();
        $userDetail = DB::table('userdetails')->where('userid', $row->sender_id)->first();
        echo '<tr>
    <th><input type="checkbox" class="select-all" value="1"></th>
    <td>' . $user->username . '</td>
    <td>' . $userDetail->accountname . '</td>
     <td>' . $receiver->username . '</td>
    <td>' . $settings->currency . '' . $row->amount . '</td>
    <td>' . $row->payment_status . '</td>';
    }
}
