Why is it possible to use the same port on TCP and UDP?

IP uses the “protocol” to pass to the next layer such as TCP and UDP though there are others. TCP and UDP each seperately differentiate connections based on the remaining 4 items. It’s possible to create other protocols on top of IP that use completely different (perhaps port-less) differentiation mechanisms.

How do I allow multiple ports simultaneously in UFW?

ufw allow 22,25,80,443,9000/tcp. Or you can add a range of ports in this way (source and more explanations): ufw allow 11200:11299/tcp. For more complicated configurations you can create a custom configuration files that could contains one or more custom profiles.
