Please note I’m not sure about the infinitive clause "to see a man ..." If the guy ran onto the balcony in order to see the man ..." then it’s infinitive clause functioning as an adverb clause. The subclause "turn and empty ..." is another infinitive clause with "man" as the grammatical subject, and "clip" the object.
The following is the clause breakdown for sentence (2):
Main clause: I was... Mr. Astley
AdvC of reason: as I am convinced ...
