Straits Settlements Queen Victoria 1883-1891 Definitive Stamps

Just bought an entire lot of Straits Settlements stamps off Ebay and one of the sets includes the Straits Settlements QV Definitive II from 1883-1891.  Have the 2c, 4c, 5c, 6c, 24c and 32c USED.  Please see the scan below.

As I have some duplicates, was thinking that it was possible to actually perhaps sell the extra ones off Ebay.  However, I am not so sure about paying a listing price when there is no confirmation that anyone will actually buy these stamps.

Queen Victoria Straits Settlements Stamps

Look what just arrived in my mail box.  A lovely set of 4 stamps from the Straits Settlements era from various Queen Victoria definitive set.  Seriously, I can't really tell the difference between all the various definitive especially for the King Edward VII sets.  They all look the same to me.  Anyway, here is a scan of the stamps:

I believe the top row (from left) is a 1882 Queen Victoria Definitive 1(b) 8 cents and 10 cents. This is followed by the carmine rose "THREE CENTS" surcharge on 32 cents.  The last stamp is a 1892-1899 Queen Victoria Definitive III 3 cent brown colored stamp.

Do let me know if I got my stamps correctly defined.
