There is no such item as Pewpew in Terraria.
The only weapons in vanilla minecraft are swords and bows (and arrows), there are no spears.
At least phaseblades and the jungle armor breastplate, but for more info go to terraria wikia

To make a furnace in Terraria, you need 20 stone, 4 wood and 1 torch. You need to stand next to a workbench in order to make it.
You most likely port forwarded wrong, or your firewall is blocking connections. Make sure the port is forwarded correctly and that the firewall is allowing terraria server.exe through. ~note by Gking19~ If you want, I'll personally help you, send me a message and I'll see what I can do.
you can't craft in terraria like you can in Minecraft but you have options of what you can "craft" in your quick menu. It just gives you things you can make with the resources you have in your inventory.
Terraria happened in 2011.
