Shop, Multi currency, Multilingual

Dear all,

I have follwing question. My target is to create an woocommerce shop mainly for polisch, german and additional internaltional market. For this purpose I did following:
-Install WordPress
-Install Woocommerce
-Install Polylang –> To create Multilingual pages and switsch symple via Button

Now I would like to give all customers the oppurtunity to pay at least via:
-Credit card
-Paypal
-Local polish pay systems (e.g. bank24 etc)

I can not understand how to set up this and how to set up that if e.g. polisch customer visit my side , he will see automatically polish currency and to have the pay in polish currency.

Can someone help me?

Best regards
ben
