Some general TESEdit advice

[Aki K]

I am trying to make most humanoid NPCs, (but especially people in towns and cities) not hostile to a particular NPC type, and likewise I want that NPC to not be hostile to those in towns and cities. What do I have to edit to accomplish this. For arguments sake, lets treat Chaurus bugs or falmer as an example. I'm eventually planning to tinker with this in a little more detail.

 

Other things I would be interested to know but less important than the above:

Is there a way via tesedit to make a spell book that summons multiple of the same NPC in a single cast? For example: if I have a spell that summons a unique version of the fire atronach can I use Tesedit so the spell summons 3 of them?
