You almost had it:
In[4]:= Function[p, #[[p]] &] /@ plist
Out[4]= {#1[[2]] &, #1[[5]] &, #1[[4]] &, #1[[6]] &, #1[[3]] &}
I suspect that you were getting tangled up in nesting the # and &
function notation. By making the outer Function[] explicit, you can
disambiguate the situation. I use this technique of using two
different notations a lot when I am faced with this kind of
introspective problem.
