The sprawling in the excerpt above suggests that: THE MEN ACT WITH INAPPROPRIATE EASE IN THE HOME. Literally, to sprawl means to sit down, lie down down or fall with one's hands and legs spread out in an ungainly way. Thus, sprawling as used in the passage above means that, the four men that are been discussed in the passage are sitting down with an inappropriate ease in a house [kitchen] that is not their own.
In colloquial English 'them" would be acceptable In formal English 'they' is used accompanied by the corresponding auxilliary verb So, you could also say Is everyone who works in this store as helpful as they are ?
