No, only two - logically that is. They have one (outside) port for DSL
connection. And one (unseen) for inside interface. And a 5port
The 4 RJ45 sockets you see labeled "LAN" are the 4 remaining ports of
the 5port hub/switch. The fifth is connected inside the router enclosure
to the inside (in both meanings) port of the router chip.

Again: these are just hub/switch outlets connected to one single
"internal side" port. Unless we are talking about professional WAN
routers (Cisco, Lucent, ...) of course...
