Check its configuration file.
Also, "netstat -nltup" will list all tcp/udp ports and program name.
You can also do "lsof" and grep for port numbers that will list the
program using the respective port(s).

Beware of using scanning tools like nmap. When you use nmap make sure
if you have the permission from the owner of the target IP. Some
ISPs may not like it even when you have the instance owner's
permission.
How can you tell if it isn't another web server running on port 80?
netstat and lsof are pretty reliable (unless your server has been
hacked and root kitted).

What do you mean by "between"?
+1 but I guess OP is asking for number of connections between his
server (client) and www.google.com (server).
Again, "netstat" and "lsof" will list the connections.
The rest of them are fundamental stuff i.e. *nix admin 101

Why not?

In what way? IMO, they should be part of your "snap your fingers" tool kit.
Where did you find such questions?
+1. To me they appear to be job interview type questions.
