Try the following lightly revisited code with some additions for account_vatnr and account_companyname additional custom fields:

// Add custom columns to Admin users listadd_action('manage_users_columns', 'add_custom_users_columns', 10, 1 );function add_custom_users_columns( $columns ) {    unset($columns['posts']);    $columns['account_verification'] = __('Verification Status');    $columns['account_vatnr'] = __('VAT Nr');    $columns['account_companyname'] = __('Company Name');    return $columns;}// fetching the verification status, thanks to LoicTheAztecadd_filter('manage_users_custom_column',  'add_data_to_custom_users_columns', 10, 3);function add_data_to_custom_users_columns( $value, $column_name, $user_id ) {    if ( 'account_verification' == $column_name ) {        if( get_user_meta( $user_id, 'is_activated', true ) == 1 ) {            $value = '<span style="color:green;font-weight:bold;">Verified</span>';        } else {            $value = '<span class="na" style="color:grey;"><em>Not Verified</em></span>';        }    } elseif( 'account_vatnr' == $column_name ) {        if( $vat_nr = get_user_meta( $user_id, 'account_vatnr', true ) ) {            $value = '<span style="color:green;font-weight:bold;">' . $vat_nr . '</span>';        } else {            $value = '<span class="na" style="color:grey;"><em>N/a</em></span>';        }    } elseif( 'account_companyname' == $column_name ) {        if( $company = get_user_meta( $user_id, 'account_companyname', true ) ) {            $value = '<span style="color:green;font-weight:bold;">' . $company . '</span>';        } else {            $value = '<span class="na" style="color:grey;"><em>N/a</em></span>';        }    }    return $value;}
