Link works for me, goes to the Minifigs site for the old "S" range. Paskal, I know you're very devoted to your Minifigs 25mm figures, but I don't think this line was some of their best work.
SAMC2 – Mounted Samurai Archer
Very difficult to tell with the crudity of the sculpture, and I can't tell what the hell is going on with the head, but from the large sode (shoulder plates), lack of sashimono (back banner), and the fact that it is a horse archer rather than a mounted lancer would suggest the figure dates not later than the 15th century.
SAM1 – Samurai with Katana
Again the helmet is oddly shaped and the crude sculpting makes it difficult to say precisely what sort of armor lacing is intended (full lacing kebiki-odoshi? paired lacing sugake-odoshi?), but the figure could be 15th-16th century. However, if those are sode extending down to the elbow then again it would probably be no later than the 15th century (the sode got much smaller, or were dispensed with altogether, in the later periods).
SAM2 – Samurai with Yari
Same comment as above – the very large sode date the figure as pre-Sengoku. A shame, as the spear (yari) was the main battlefield weapon for the samurai in the later period, which this armor is wrong for. And once again the correct shape for the kabuto (helmet) has totally eluded the sculptor.
SAM3 – Ashigaru with Katana
Not a totally terrible ashigaru from the 16th century (which the jingasa war-hat would indicate), but a katana is a very odd weapon to show an ashigaru (peasant warrior) wielding. They were typically issued spears or missile weapons, with a wakizashi short sword as backup.
SAM6 – Ashigaru with Yari
Good to show an ashigaru with a spear, which along with the matchlock musket is their most common armament. But where is his armor? This would appear to be a common peasant, maybe an ikko-ikki rebelious farmer.
SAM8 – Samurai Archer
The large sode and lack of arm protection, as well as the use of the bow, indicate earlier period. The bare feet is confirmed in many battle screens – for retainers and low-ranking samurai only, however (the ones on foot, during this period where horse-archery was the most important combat role). The helmet once again is absurd.
SAM9 – Samurai with Matchlock
It's quite true that some musketmen were samurai and that they weren't all ashigaru. But by the time of musket use (post 1543), it would be very rare to see a bare-legged samurai. The vastly increased importance of dismounted close combat from the mid-14th century onwards put a premium on leg and arm protection, for anyone who could afford it.
