According to /v/ standards it's whenever You Personally stop playing it. (re: the dozens of Team Fortress 2 is dead shitposts)
Practical standards it's when you can no longer find a decently full match at reasonable ping.
When the servers shut down i guess
when there's zero players. it will stop being dead if it goes back up to 1 player though
When most of its reviews are negative and about hackers, bad servers or abandoned by devs
Depends on the genre and style.
When a game drops below 50,000 viewers on Twitch. That's what /v/ tells me

No, you'd need at least 2 players for a match.

I think there are people on /v/ capable of describing singleplayer games as dead
Compare with battleborn numbers
