My best guesses at how to resolve the peculiarities:

• Line 2: Alcyone is Greek; the y (for υ) is short and the final e (for η) is long.
• Line 4: The first syllable (lacr-) of lacrimis can be short because a stop (c) followed by a liquid (r) can be short.
• Lines 5,6: Qu is counted as a single sound.
• Line 8: Ubi est could be pronounced Ub’ est or Ubi ’st.
