1) All enemies have limited spawns which can only be reset either by joining the Company of Champions or by burning a Bonfire Ascetic.

2) You need to be human, online, and in an area where you can invade. Also make sure that in the area you're trying to invade, you select "Nullify Effigy effect" at the bonfire. And as for the error message, you may want to make sure that you have Cross Region Play allowed as it opens up online play substantially.

4) Yes.

5) Kill their necromancer.

Hope this helps! :)
