    jQuery.validator.addMethod("alphanumericspecial", function(value, element) {
        return this.optional(element) || value == value.match(/^[-a-zA-Z0-9_ ]+$/);
        }, "Only letters, Numbers & Space/underscore Allowed.");

    jQuery.validator.addMethod("alpha", function(value, element) {
return this.optional(element) || value == value.match(/^[a-zA-Z]+$/);
},"Only Characters Allowed.");

    jQuery.validator.addMethod("alphanumeric", function(value, element) {
return this.optional(element) || value == value.match(/^[a-z0-9A-Z#]+$/);
},"Only Characters, Numbers & Hash Allowed.");

U can create functions easily like this bro..

You will need to add extra method to validation library, like that:

$.validator.addMethod("alpha", function(value,element)
{
   return this.optional(element) || /^[a-zA-Z]$/i.test(value); 
}, "Alphabets only");

Then you can add it to your validation rules.

Otherwise, you can define generic "regexp" rule, as described in this answer
