What exactly do you want to know?
I noticed the LAH and NaBH₄ reactions are missing a product!
Otherwise there is really a lot to look at here.

ya..they are not relevant to our syllabus..

I wanted to check whether I've done it correctly...

It looks OK, except I would not call the diazonium salt reaction a hydrolysis, this is the Sandmeyer reaction.
And the other products produced in a reaction are always relevant and you should know what they are, syllabus or not.

you need to step back and think about what's going on with each molecule you've posted.  if you try to hydrolyze a basic organic compound with a strong base, do you think it's going to do anything?  if you try to hydrolyze an acidic organic compound with a strong acid, do you think it's going to do anything?

i.e. if you throw in a bunch of NaOH crystals in a solution of phenyllithium, is anything going to actually happen in your flask?
if you throw in a bunch of TfOH in a solution of phenyllithium, is anything going to happen in your flask?
