A router may have multiple addresses depending on the number of interfaces to other networks. For a router to function effectively it must have at least 2 addresses, but some routers may have more.
They Should only have one.
It depends on how many interfaces of router are connected to other networks. If a router is connected to two network, it will have 2 IP addresses. In a router having 4 ports it can connect to maximum 4 networks. In this case it will have 4 IP addresses.
Your Router is assigned an IP address that is known as a public IP address then your router assigns out IP addresses that are known as local IP addresses. So the answer is yes and yes!
They are normally the IP addresses which your computer uses to talk to your internet router/modem. They are not the same as the IP address that your router is known by on the broadband link.

A router or switch.
Since Facebook uses a limited range of IP addresses, blocking those addresses on the router will effectively deny access to Facebook.

Read the section of the manual concerning enabling the router to be a DHCP server. DHCP is the magic that assigns IP numbers.
Yes, in fact, every interface (or port) in the router must have not only a different IP address, but IP addresses in different networks, if those interfaces are to participate in IP routing.
