What does a move entail?
1A: Kill 1 Zombie:


  After moving into a Room, you may kill 1 Zombie. [...]


So 1A can be performed each time you enter a room.

1B: Use Room's Ability and/or Interact with a Token:


  After moving into a Room (and killing a Zombie if necessary), [...] you may then use Room abilities and/or interact with Tokens. [...]


So 1B can clearly be done in addition to 1A. There's no reason to believe 1C is any different, so all of 1A to 1C can be done each time you enter a room.

Since you have three moves, you shall be entering three rooms, and thus go through 1A to 1C three times.

Then, you search your current store


  After completing 3 Moves, the Human Player flips over the facedown
  Search Card in front of them and places this card face up next to the
  Store they are in. [...]


So, in the right conditions, you could perform 10 actions per turn (13 if you count "Use Room's Ability" and "Interact with a Token" separately). Keep in mind the some actions (1B and 1C) can only be taken if the store is devoid of zombies.
