Hello seratjati,
Welcome to the Headstart Community and that's an excellent question!
Provided all those email addresses are registered to the same account and confirmed, it doesn't really matter which email address your customers send funds to, it will end up in the same account balance.
For example, if I send you funds at an email address which you added to your PayPal account, but is not your primary one, you will receive those funds and reflect on your account balance the same way they would if I were to send the funds to your primary email address. Hope that makes sense. 🙂
