Can I block internet access for almost everything?

Is there some way I can block internet access for everything save a few exceptions (four or five applications)?

Yes, iptables supports it. You can web search “ iptables filter by application” to learn more details.

Yes, and you could also install a Web Application Firewall aka a WAF depending on your use case scenario.
