How many peaks the carbon-13 MNR spectrum of cyclohexylmethanol would have? Won't they be 4?

Thats what I got but the mark scheme says 5
It is 5. The middle 4 peak you labelled is the 5th one as it has a different carbon environment to the other two 4 peaks you labelled.
C5 is attached to C2H4CH(C2H4)CH2OH
C4’s are attached to CH2 of the 5 and then the rest of the chain which is different to C5’s environment.
Hope that helps

So we do not look at the immediate environment only but also that of the neighboring carbon?
