I think out of the non master models you got there the main case for auto include is Samael. His range is a little short for such a shooty model, but get him in a good spot to Rapid Fire with Flaming Bullets up and he can make a big hole in most lists.
I favour Witchlings over Death Marshals in the 4 points bracket, they have a few more options available to them that disrupt your opponent, other than the tricky Pine Box spell. However with Justice, a single Death Marshal might be handy to boost her already considerable melee damage potential.
Given your options and my preference for Criid, I'd go something like:
Criid
Flame
Sam
Executioner
2 Witchlings
Judge
7 Cache
If you want Justice as master could just be a case of trade Criid and her totem and maybe the Witchlings for Marshals.
