I am soi confused. Please help me (Setting up a website and custom email address)

Hello

Thanks  in advance. I purchased a bunch of doomains for my business. I just want an email and website.

Google is charging me for 2 seats and ?I cant figure out how to get it to cgarge me for 1 . Caan I set up aliases for my domain and not get charged for another user? Do I not get a website from google? Do I have to purchase a squarespace account and pay for google as well? I thought I got free email if I purchased a site.

Can someone just tell me what I have to buy to just have an amail and a site PLEASE
