I agree it's pretty straightforward.

Can anyone tell me what "5-K-1" and "P-S-I" are?

5k1 is a court motion requested by the prosecution during the sentencing phase. It requests the court to reduce a defendants sentence because of cooperation with law enforcement.

PSI is simply a presentence investigation. It would state whether or not the defendant cooperated with law enforcement.

The meaning of the lyrics is simply "F" anyone associated with a 5k1 motion because that usually means they cooperated with law enforcement (SNITCHED). "Check his PSI" suggests to look at the persons presentence investigation to see whether or not they (SNITCHED).
