i try to create some many npc with aggressive lv 2 .

i give them the same faction.

so many time they hit other npc near them.

i just want them to attack player only.

do u have any idea ?

any package can do this ?

Make them aggresive (level 1) and make her faction enemy to player faction. If you make the very aggresive (level 2), they will attack to anyone not being friend or ally, while being aggresive (level 1) they attack only to enemies.

Also, an actor is not automatically friend or ally to members of the same faction. For that, you need to make the faction ally or friend to itself.

Create a relationship between the NPC and player, and make the player the enemy. You're sure to get attacked that way.
