You could try something like this :

add_action( 'cw_shop_page_attribute', 'cw_shop_page_attribute', 25 );
function cw_shop_page_attribute() {
global $product;
$attributes = array(
    'display-size' => 'Display',
    'processor-type' => 'Processor',
    'primary-camera' => 'Rear Camera',
    'secondary-camera' => 'Front Camera',
    'internal-storage-gb' => 'Storage',
    'ram-gb' => 'RAM',
);
$counter = 0;
foreach($attributes as $attribute_name => $attribute_label) {
    $attribute_value = $product->get_attribute($attribute_name);
    if( !empty($attribute_value) && $counter < 3 ) {
        echo '<tr ><td ><i ></i></td>';
        echo '<td >' . $attribute_label . '</td>';
        echo '<td >' . $attribute_value . '</td></tr>';
        $counter  ;
    }
}
}

get_attribute() returns a comma separated string of the values, so you can use php's explode function to loop through the values as an array and then bail after 3 results have been returned.

For example:

if ( $display_size ) {
    echo'<tr ><td ><i ></i></td><td >Display</td>';
    $display_size_array = explode( ',', $display_size );
    $count = 0;
    foreach ( $display_size_array as $attribute ) {
        if ( $count >= 3 ) {
            break;
        }
        echo'<td >' . $attribute . '</td';
        $count  ;
    }
    echo'></tr>';
}
