Yes, that's how this problem should be started.

Of course. This was mentioned in class.

Yes, the explanation of the differences between Reynolds and Blasius can be “verbal”. That is, you can simply put down in written form the verbal explanation you would give to others as to why there is a large discrepancy. You can include some math expressions if this makes your explanation easier to follow. Note that both are exact solutions.

You need to explain why there are discrepancies between the solutions obtained despite the latter all originating from the Navier-Stokes and despite Reynolds and Blasius being both exact solutions to the boundary layer phenomenon. How is this possible? Explain things in simple terms so that they are readily understandable to someone with basic knowledge in fluid mechanics.

See my answers above for similar questions. You need to make sure that the way you define the height works well equally when $u_w$ is much less than $u_\infty$ and when $u_w$ everywhere in the profile is more than 0.99999999$u_\infty$. I mentioned in class specifically that (a) is improper. Why are you writing this here? As for (b), I see many problems with a $v$ on the denominator.. Ask yourself this question: where is $v$ approaching 0? This will occur at several locations..
