You need only refer to one text from the stimulus booklet, yes. Be aware that they can specify, or ask for more than one, but it is highly unlikely.
No, they can neither specify nor ask for more than one.
This is written on the stimulus booklet:
This booklet is a prescribed text. In the HSC examination
students may be asked to refer to at least one text that
they have selected from the stimulus booklet.
At least one text. So that means that they can not force you to do two texts and certainly cant force you to write about a specific one as the above says "a text that THEY have chosen"
