In Chapter Five, as Cassie, Big Ma, Stacey, and TJ head for the market in Strawberry, it is three-thirty in the morning, and TJ is initially subdued—"but by dawn, when the December sun was creeping warily upward" he is "chattering like a cockatoo."
Wariness is a behavior attributable to people (or animals), not the sun, so this description is personification. The comparison of TJ to a bird is a simile.
In Chapter Six, Uncle Hammer speeds off to confront Mr. Simms about manhandling Cassie as "the car zoomed angrily down the drive"; this is another use of personification since anger is a human emotion that a car can't possess.
Later in Chapter Six, as Cassie and Mama prepare to go to church, the author uses a simile to describe Mama's hair; "it fanned her head like an enormous black halo" and Cassie observes that Mama "always smelled of sunshine and soap." While soap does have a fragrance, smelling of "sunshine" is a figurative description.
In Chapter Seven, after Mr. Morrison tells frightening stories about Civil War raids, including one in which he lost his family, Cassie has an uneasy night disturbed by "visions of night riders and fire mixed in a caldron (sic) of fear." The cauldron of fear is figurative.
