function custom_woocommerce_billing_fields( $fields ) {
$fields['billing']['billing_options'] = array(
'label' => __('Custom Field', 'woocommerce'), // Add custom field label
'placeholder' => _x('Custom Field', 'placeholder', 'woocommerce'), // Add custom field placeholder
'required' => false, // if field is required or not
'clear' => false, // add clear or not
'type' => 'text', // add field type
'class' => array('own-css-name') // add class name

To delete an existing field, country for example:
add_filter( 'woocommerce_billing_fields' , 'custom_override_billing_fields' );
function custom_override_billing_fields( $fields ) {
unset($fields['billing_country']);
return $fields;
}

Answer 3

maybe the best way use woocommerce_default_address_fields - is it ?
for example as
#5447232
add_filter( 'woocommerce_default_address_fields', 'add_MyNewOption_address' );
function add_MyNewOption_address( $fields ) {
$fields['MyNewOption'] = array(
'label' => __('Custom Field', 'woocommerce'), // Add custom field label
'placeholder' => _x('Custom Field', 'placeholder', 'woocommerce'), // Add custom field placeholder
'required' => false, // if field is required or not
'clear' => false, // add clear or not
'type' => 'text', // add field type
'class' => array('own-css-name') // add class name
);
return $fields;
}
