After a week of nonstop listening, I think they are characters in Redford's life

Krit is Redfords spirit. His verse is Redford's one on one conversation with God, asking for mercy and pleading for forgiveness and understanding about his situation and the choices he made in the absence of alternatives, etc...

Phonte is Redfords assassin. His verse is a detailed account of getting geared up and ready for taking Redford out

Porn, Dice and Truck are Redfords crew

Porn is the baller. The guy that's all flash, Slick Rick jewelry and Jay Leno cars. He probably dies before Redford.

Dice is the reluctant hustler. He's got a conscious and questions the decisions they made from the beginning. He probably survives and finds a life outside of the game

Truck is muscle. He's probably satisfied with the status they have in the neighborhood and doesn't have a desire to rise much above a street level cat.

Redford, Porn, and Truck remind me of the characters in Paid in Full. Redford being Wood Harris' character. Quiet, low-key hustler, but he's got all the juice. Porn would be Mekhi Pfifer's character, his need to be in the game is strictly material. Truck is Camron's character, always on the block and into dirt.
