Reverse proxies windows -> intermediate server -> internet, how to implement?

Question

linux

I have such a bunch: several computers that are at home, 3 pieces (at home, and friends with whom we want to make proxies), there is a server with an external ip on linux, you need to make reverse proxies so that you can use home computers as a proxy. windows (behind NAT) -> intermediate server with port -> proxy.
For each computer, a separate port is opened on the server with a dedicated IP. At the output, we get a proxy (for example, socks5) which can already be used in curl or a browser, for example, and there will be IP = IP of the home windows PC. By the way, there is a similar thing in botnets, it seems - using computers as a proxy, so how can I play this with my home computers? It is clear that you need to have an intermediate server, but how to connect everything.
