Zoraida has a couple of unusual abilities when it comes to hiring out of faction models, and for my own reference I've put together a list of what she can take outside of her usual declared faction. I've not listed below all of her in faction models which will naturally depends on whether you take her as Neverborn or Gremlin.
Her hiring restrictions are affected by two rules, one on her card...
Enthrall: This model's Crew may hire any Living model with a Wp 4 or less as if it had the Mercenary characteristic.
...and one on her 2SS Tarot Reading upgrade:
Bayou Servants: Crews containing this model may hire Swampfiend models regardless of faction.
Note on Enthrall, you have to hire them as if they were Mercenaries so you pay +1 SS and can only take a maximum of 2 Mercenaries. For the sake of completeness, I've included all models with the Mercenary characteristic.
Here is a breakdown of options by faction with a summary of the rule required:
Papa Loco (Enthrall)
Malifaux Raptor (Enthrall)
Silent One (Enthrall)
NEVERBORN (assuming you're using Gremlin Zoraida, Neverborn Zoraida has whole faction available)
Bad Juju (Bayou Servants)
Voodoo Doll (Dual Faction)
Silurid (Enthrall, Bayou Servants)
Waldgeist (Bayou Servants)
Spawn Mother (Bayou Servants)
Gupps (Bayou Servants)
The Depleted (Enthrall)
Student Of Conflict (Mercenary)
Malifaux Child (Mercenary)
Convict Gunslinger (Mercenary)
Desperate Mercenary (Mercenary)
Freikorps Specialist (Mercenary)
Freikorps Librarian (Mercenary)

Rooster Rider (Enthrall)
Gremlin Taxidermist (Enthrall)

Bayou Gator (Bayou Servants)
Illuminated (Dual Faction Neverborn, Neverborn Zoraida only)
Mr Graves (Dual Faction Neverborn, Neverborn Zoraida only)

I believe this to be a complete list of both wave 1 and wave 2. Please let me know in the comments if you spot any mistakes or omissions.
