sure. just add the following code to your theme’s functions.php:

function add_extra_contactmethod( $contactmethods ) {
    // Add new ones
    $contactmethods['twitter'] = 'Twitter';
    $contactmethods['facebook'] = 'Facebook';
    $contactmethods['googleplus'] = 'Google Plus';
    $contactmethods['youtube'] = 'Youtube Kanal';

    // remove unwanted
    unset($contactmethods['aim']);
    unset($contactmethods['jabber']);
    unset($contactmethods['yim']);

    return $contactmethods;
}
add_filter('user_contactmethods', 'add_extra_contactmethod');

this removes “aim, jabber and yim” but adds twitter, facebook, yt and googleplus
