Your relative clauses list:
‘Who’ is widely accepted instead of ‘whom’, which is often viewed as stilted and old fashioned these days. However, the structures are all okay.
Make somebody do…
The ‘and’ in the first sentence sounds a little more awkward and less fluent than the ‘to’ in the other two sentences, but the second and third sentences are too awkward with the ‘me’. It’s unnecessary and should be omitted:
Even these are awkward and personally I would find another way to say them, using more than one sentence if necessary.
She asked me if I could try to make him stop seeing her daughter.
Is this the boy who/whom (see note above) you want me to make stop seeing your daughter.
This is the boy who/whom she’d like me to make stop seeing her daughter.
Undoubtedly… and I still use ‘whilst’ too.
Perhaps I should have stuck to my guns and not been so lenient about it (I’m certainly not so lenient about a range of other modern permutations) but I wanted Alexandro to be aware of what he was likely to see elsewhere.
It was late*… I was tired… I was weak-willed.
In Alexandro’s examples there is really no need to fret about the ‘who/whom’ question because the simplest thing is to leave out the relative pronoun (object) altogether. ‘Whom’ is best left when it is in a stressed position after a proposition. Hanging on to fads about usage doesn’t really help anyone.
