I need to tidy the unused rules (63) However can I just delete them? As I am not sure whether these are connected to other processes, it's the same for the NAT rules.
You may delete the firewall rule if there is no traffic passes through it. However, it is better to disable the rule for now and if you don't see any issues in the services. Later, you may go ahead and remove it.
