The salutation you can add according to your requirement and by default the selected salutation will be selected at the time of entering the customer name while registering the customer profile.
Then “Customer’s Email Address is Required”, you can also make the customer’s email address mandatory by enabling this option, as a result without entering the email address, you can not register the customer.
