Much of your questions are answered on the idle battle page. In the idle page, on the left side below the challenges button there should be one that says battles. You can also see your points and where the next reward is
1) at least 10 players must join for an idle battle. They start every 30 minutes.
2) auto conquer is forced on so you auto take land
3) in battles, mortars attack other players. On the right side there is a pop out button, it shows the other players status and you can select who you attack
4) active artifacts are powerful in battles. Super charge army camp and time warp are the best IMO
5) Players who have been playing for years will have lots of advancements and high level
artifacts and can clear some of the maps quickly
6) That’s up to you. Look at the rewards and if it is worth spending time to get the first few rewards, but you are likely far away from getting in the top 5 for the better rewards
For the other questions, take a look at an idle guide. Reward structure for battles is at the bottom of this one
