You would need to ask the game publisher or developer. In most cases, playing a video game while adding your own commentary to your gameplay constitutes fair use.
Search "Terraria invedit" on youtube.
There aren't really Terraria "accounts". You just play the game without logging in.
There are no main server on terraria so I would suggest google searching "terraria servers" and see what comes up. I have done this and been on multiplayer.
Nope.That is if u mean talk in terraria with your voice(using terraria)no.You can use other free programs like skype-you can talk with your mic there and write for free.So just talk in skype and play terraria.

You have to get permission from the video game company before you can publish your videos on YouTube.
uhh... i doubt that there is one. People normally use cheats or play it regularly to get what they want on Terraria Edit: Single Player Commands are available.
I would advise you Terraria and Ark: Survival Evolved, although you probably already heard about these games. Of the less popular games, I advise Realmcraft, it is very cool :)
It depends on the website you download it from, some might be unsafe that give you viruses or even possibly scamming you but some are safe but i recommend you buying it on Steam for legal and safe reasons
There is no free version. You have to buy it to play it.
No, you can buy it at terraria.com or on steam for 10 bucks
Not without permission.
