#2 is in Fine 6.0 range with nice cover color/gloss, together well at staples, sharp edges and corners, flat/tight.  Most defects are the stress marks on the spine.

#3 is low grade because lower front cover has had a sticker pull tear lifting the colors.  If not for that, similar to #2 but more in VG+ range.

#4 is G/VG with lots of general stressing from handling/storage.  No major defects, just an accumulation of stressing/creasing/wrinkling, and minor tears.

#5 is very similar to #4.

All for one price.
