Switch for small LAN, Router for two or more
I'm pretty sure LAN's are a group of computers connected to each other through routers/modems or ethernet cables. The internet it similar to LAN's but instead of connecting to other computers close by, it connects to computers all around the world.
LAN is wired WLAN is wireless

A router.
For a small LAN network, a switch is best. To connect two or more LAN networks, a router is required. (2) From Jean Andrews CompTIA A+ sixth edition (page #852): You can use a crossover cable to connect to computers without a switch or hub making it the simplest network of all. For two or more you will need a switch, hub, or router.
Connecting different networks requires a router
Any device on a LAN is called a node.

It's called a switch. Many wireless routers have a 4-port switch. Also you can purchase a switch separately.
Yes, but the data traffic will traverse the Internet to reach that public IP address. If the server has another network interface in the same subnet as the connecting device, you can constrain the traffic to the LAN. If the connecting device is instructed to use the public IP address to reach the server, the traffic will first travel to the LAN gateway, which determines the best route for the traffic to reach public addresses. Typically, this would be via an ISP that the gateway is somehow connected to. Please specify your goal in your question to get an optimal strategy as an answer.
