Answer 1

You need to have your mod % either close the li or open the li , not deal with the div .

So something like this:

$counter = 1;
while($row = mysql_fetch_array($result)) {
    if ( $counter % 5 == 1 ) {           
        echo '<li>';
    }
    echo '<div class="title">'.$row['title'].'</div>';
    if ( $counter % 5 == 0 ) {           
        echo '</li>';
    }
    $counter ++;
}
if ( $counter % 5 != 1 ) {           
    echo '</li>';
}

Haven't tested it, but it should help set you on the right path.

You seem very close, how about:

$counter = 0;
while($row = mysql_fetch_array($result)){
        if (($counter % 5) == 0) {
            echo '<li>';
        }
        echo '<div class="title">'.$row['title'].'</div>';
        if (($counter % 5) == 4) {
            echo '</li>';
        }
        $counter ++;
    }
}
if ($counter % 5 != 4) {           
    echo '</li>';
}

Answer 3

$x = mysqli_num_rows($result);   
$counter = 0;

while($row = mysql_fetch_array($result)){
if ( ($counter % 5) == 0 ){
echo '<li>'
}           
echo '<div class="title">'.$row['title'].'</div>';
if (((($counter +1) % 5) == 0) || (($counter+1)==$x)){
echo '</li>'
} 
$counter ++;
}

I did not check it but the mysqli_num_rows variable can be used to close last.
