Every page has it’s own seprate currency

I have created 5 different homepages for the customer and I need the functionality that when someone visit homepage 1 it should have UAE currency, or when someone click homepage 2 they should visit KSA currency, like this in all page.

I don’t want to show them the currency widget, when they click certain homepage only the currency assigned to that page should be visible.

Can you please help me with how I can achieve it?
