Answer 1

$('#billing_first_name').on('input',function(){
var node = $(this);
node.val(node.val().replace(/[^a-z]/g,'') ); }
);
Adding this jQuery will work.! You can add for others fields too.

Answer 2

You have to add fields by custom method then use follow script for alphabetic textbox:
add_filter('woocommerce_checkout_fields', 'custom_override_checkout_fields');
function custom_override_checkout_fields($fields)
{
$fields['billing']['billing_first_name'] = array(
'label' => __('First name', 'woocommerce'),
'placeholder' => _x('First name', 'placeholder', 'woocommerce'),
'required' => false,
'clear' => false,
'type' => 'text',
'class' => array(
'alpha'
)
);
and same for billing_last_name,
use all of scripts in active theme functions.php
Actually woo-commerce does not give us this functionality. You have to use your custom jquery or javascript. This might help you
You should call this script under wp_head hook
add_action('wp_head', ' alphabet_only ');
function alphabet_only() {
?>
<script type="text/javascript">
$('.alpha').bind('keyup blur',function(){
var node = $(this);
node.val(node.val().replace(/[^a-z]/g,'') ); }
);
</script>
<?php
}
That's it.
