Dabura >> Cell >> Bojack

Super Perfect Cell, fought a weakened Super Saiyan 2 Gohan had lost, even if he was distracted the raw power of Gohan's Kamehameha destroyed him. Even though the newly recharged Cell was more power than Gohan at the time. Cell's strength was never shown though apart from the Kamehameha attack he launch on SSj2 Gohan. He is shown to be clearly stronger as throughout the majority of the beam struggle Super Perfect Cell seemed to be the stronger of the two.

Bojack easily beat Vegeta, and Piccolo that puts him above Cell in terms of strength, but he even survived a Kamehameha warfare as it was canceled out with Gohan.
Bojack was stronger as he still had the energy to keep standing. The movie did present SSj2 Gohan to be stronger by Gohan by huge amounts unlike Super Perfect Cell.

Dabura: with an older, weaker Gohan who is stated to be weaker than when he battled Cell. This statement by Vegeta puts Dabura right at the bottom, as even he seemed to struggled whilst fighting Gohan (doesn't matter what Super Saiyan Level he was in), only to conclude their fight with him leaving.
