As the distances are close due to the nature of the environment I assume melee range tough you will not take the in melee penalty before you are actually attacked:
order is:
1. Kynos 22 - shoots undead 1 - 2 hits full auto:
2. Undead 1: 21 - Attack Irris (6 hits) if hits 9P + net hits damage (note that the armor will likely convert it to stun).
3. Ayato: 20 -
4. Undead 2: 20 - Attack Kynos 3 hits - will miss.
5. Undead 3: 18 - Attack Ayato 2 hits - (will miss?)
6. Irris - 13 - (must resolve rat situation before she can fend for herself).
The 3 smugglers since you disarmed them are not going to participate, either they are paralyzed with fear by the swarm of rats biting them or they are already vast asleep. Whatever seems to fit more with your timeline as I kind of intercepted you in the way to the car.
The undead roll 12 dice to dodge, but use full defense to add 6 more dice if attacked, so they are going to be a bit tricky to hit (18 dice to dodge). Feel free to roll for them if you want to resolve quicker.
Oh and for damage, they get 9 dice to resist damage with body and they wear no armor. (12 physical track, 11 stun).
Resolution:
1. Kynos shoots undead 1 with full auto burst and misses.
Undead 1 goes full defense +6 to defense
dodge kynos -5 + full defense:
13d6t5 32. Undead 1 attacks Irris with 6 hits - ...
