    From the current user ID you can get all its related metadata with get_user_meta() like:

    // Get all user metadata in an array
$user_meta = get_user_meta( get_current_user_id(), false, true );

// Display the metadata array
echo '<pre>'. print_r( $user_meta, true ) . '</pre>';

    You can get all user_meta and then find the ones you need. For example, something like this:

    $new_user_id = 1 ;
update_user_meta( get_current_user_id(), "add-user-id-$new_user_id", $new_user_id );

$new_user_id = 2 ;
update_user_meta( get_current_user_id(), "add-user-id-$new_user_id", $new_user_id );

$find_meta_ids = [1, 2];
$find_key_prefix = 'add-user-id-';

$output = [];
$all_meta = get_user_meta( get_current_user_id() );

foreach ( $all_meta as $key => $value ) {
    $key_id = array_pop( explode( $find_key_prefix, $key ) );
    if( in_array( $key_id, $find_meta_ids ) ) {
        $output[$key] = $value[0];
    }
}

var_dump( $output );

    Result: array(2) { ["add-user-id-1"]=> string(1) "1" ["add-user-id-2"]=> string(1) "2" }
