In order for a server to fully function as a web server, two default ports that should be open are port 80 and port 443.
Port 80 is the default port used for HTTP (Hypertext Transfer Protocol) traffic, which is the protocol used to transmit web pages from the server to the client's web browser. This port must be open to allow clients to connect to the web server and retrieve web pages.
Port 443 is the default port used for HTTPS (HTTP Secure) traffic, which is a secure version of HTTP that uses SSL/TLS encryption to protect sensitive data such as login credentials and payment information. This port must be open to allow clients to connect to the web server securely.
The other ports listed in the question are not required for a web server to function. Port 22 is used for SSH (Secure Shell) traffic, which is used for remote administration of the server. Port 445 is used for SMB (Server Message Block) traffic, which is used for file sharing on Windows networks. Port 631 is used for IPP (Internet Printing Protocol) traffic, which is used for printing over the internet. Port 8080 is an alternate port used for HTTP traffic, but it is not a default port for web servers.
