Here are my take on these diss songs

Guy Guy Fall says that Roga Roga only cares about getting things for himself (that we know is true)

Oxygene refers to Roga Roga as Judas (implying that Roga Roga denied his friends anything and lack of gratitude since they helped him get his fame)

wrong. Oxygene sung about the bad things Roga Roga did behind the scene to kill his career. Talking bad about Oxygene to donors, doing witchcraft, calling people not produce to him, etc. with Oxygene advicing Roga to repent for his sins and go towards god.

Guy-Guy fall's song was about how bad Roga Roga is in his opinion, saying that he has a bad heart and dont want to see people succeed and if he see people succeed then its a big problem.
