Space Hulk: Ангел Смерти

No — a player may not choose an Action card that he resolved during the previous game round; keep chosen Action cards on the table until the end of the next Choose Actions Phase to remember (Rulebook p.11).

No — Support Tokens can only be spent to reroll dice rolled for an attack or a defense, and only if the Space Marine is facing the attacking or defending swarm; they cannot be used on non-attack rolls like Heroic Charge (Rulebook pp.15–16).

No — a Space Marine may only spend Support Tokens or attack/defend against Genestealers that he is facing, so a swarm attacking from behind cannot be rerolled or defended with Support Tokens (Rulebook p.16).

No — when you swap a Space Marine with an adjacent card, all Terrain cards and Genestealers remain in the position the moved Marine left (they do not move with him) (Rulebook p.17).

Spawns are always drawn from the blip pile on that side; if that blip pile is empty then those Genestealers are not spawned, and if there are fewer cards than needed you spawn as many as possible of your choice (Rulebook pp.21–22).

No — engaged Genestealers remain in the formation during travel; they only leave play via specific Terrain abilities (e.g., Door), being discarded, or being slain (Rulebook p.25).
