If these are addresses that you will use from time to time then you should add them into your paypal account. Then whenever you want to send it to them you would choose that address. If they're not addresses you will use all the time then do it the way I said. When you go to pay for an item you click on pay now. Then you choose to pay each seller seperately. That will take you to the orders details page. On the top left will be your address and a link in blue that says change. Click on that and put in the address you want to send it to. Then just proceed to pay as usual. The address will only be used for that one transaction this way and you will still have buyer protection.
You do not want to make any of these addresses your primary shipping address - that is for your address.
