Do any of the manga from Bakuman exist in real life? Do any of the manga from Bakuman exist in real life? Are there any plans to make some of them? I would especially love to read Classroom of Truth.
There are two direct official adaptations of Bakuman's manga in real life.



Otter 11

As @ʞɹɐzǝɹ said, Otter 11 has been published in Shonen Jump as a oneshot by Takeshi Obata(Art) and Tsugumi Oba(Story), which are the same persons that made Bakuman. 





PCP (Perfect Crime Party)

PCP has been adapted as a novel by Takeshi Obata(Art) which is the illustrator of Bakuman, and Sei Hatsuno(Story).
