If i have i.e. 9 different pictures of blood and i want that it splatters over my level models when i kill an enemy, how can i do that?

I think i should use decals but do they work on the iPhone with less drawcals?
There is this kit for free 110 - 开云官方入口 and also one in the asset store but i do not know if it is working good on the iPhone.

you can turn them into particles and give them world particle colliders. That should get them to stop and stick to something after it emits from your unit.
