The images were mixed up. While the first link shows a male costume, the description refers to it as having been worn by Christie Haydon, clearly female. ;-) Here's her page on Memory Alpha: Christie Haydon
The second costume is listed as "male" though it is the costume worn by Christie Haydon in Unification I.
STAR TREK: TNG “ENTERPRISE-D BARBER SHOP ATTENDANT"
http://cgi.ebay.com/STAR-TREK-TNG-ENTERPRI...1QQcmdZViewItem
only worn by "customers" of the barbershop, such as Beverly Crusher in "The host", for example here
STAR TREK: "ALIEN BACKLIT DISPLAY"
http://cgi.ebay.com/STAR-TREK-ALIEN-BACKLI...1QQcmdZViewItem
This is a Dominion interface, first seen in the relay station on Callinon in the episode "The Search I". Here's a screencap:
STAR TREK: TNG “ALIEN CAPTAIN JACKET"
http://cgi.ebay.com/STAR-TREK-TNG-ALIEN-CA...1QQcmdZViewItem
The "alien Captain" is actually the Captain of a Corvallen freighter seen in "Face of the enemy": entry at Memory Alpha
STAR TREK: DS9 “PROMENADE ALIEN” COSTUME
http://cgi.ebay.com/STAR-TREK-DS9-PROMENAD...1QQcmdZViewItem
The costume worn by the Rasiinian ambassador in "The muse". The complete story behind that character and the creation of the costume can be found here
STAR TREK: DS9 “TALL PROMENADE ALIEN” COSTUME
http://cgi.ebay.com/STAR-TREK-DS9-TALL-PRO...1QQcmdZViewItem
Those aliens can be seen in several early DS9 episodes, more info here at MA
STAR TREK: TNG “THE HUNTED – ANGOSIAN POLICE”
http://cgi.ebay.com/STAR-TREK-TNG-THE-HUNT...1QQcmdZViewItem
This uniform was worn by the co-pilot of the Angosian transport (the Captain being Wagnor). The tearing in the costume is due to the removal of the Angosian badge, worn by all Angosians (except for the escaped prisoners) in this episode. The co-pilot can be seen here.
STAR TREK: DS9 “GRAND NAGUS STAFF”
http://cgi.ebay.com/STAR-TREK-DS9-GRAND-NA...1QQcmdZViewItem
This is actually the staff used by Neelix, disguised as the Ferengi Grand Proxy, in the VOY episode "False profits". When the two stranded Ferengi, Kol and Arridor, decide not to obey the "Grand Proxy" 's demands and want to kill him using swords, Neelix uses the staff for protection. While doing so, it is hit by one of the swords, breaking in half at the exact spot where this staff is broken, explaining why the lower half is missing. So, this is likely a replica of the staff used in all of DS9, as the complete scepter was seen in later DS9 episodes, aired after "False profits". Here's a screenshot of the scene:
STAR TREK: DS9 “ODO – FOUNDERS VIRUS” COSTUME
http://cgi.ebay.com/STAR-TREK-DS9-ODO-FOUN...1QQcmdZViewItem
Another error: This is NOT a costume worn by Rene Auberjonois in the final DS9 episodes, when Odo was affected by the Founder virus, but it is the costume he wore in the Season 3 episode "The die is cast", when he was tortured by Garak and was not able to change shape. Compare the various screenshots here with the uniform up for auction - they are completely identical. When Odo was affected by the Founder virus, in "Tacking into the wind" and "Extreme measures", for example, he wore a civilian outfit, because he was on an undercover mission together with Major Kira. The melted costume he wore in those episode can be seen here for example - looks completely different.
STAR TREK: DS9 “MILES O’BRIEN – STARFLEET UNIFORM”
http://cgi.ebay.com/STAR-TREK-DS9-MILES-O-...1QQcmdZViewItem
Although not actually shown on screen, this may be from "Extreme Measures", when Sloan's brain security guard (heh) shoots O'Brien. His hand covers a wound spot exactly where the shot is on this costume.
STAR TREK: TNG “CAPTAIN PICARD” CIVILIAN COSTUME
http://cgi.ebay.com/STAR-TREK-TNG-CAPTAIN-...1QQcmdZViewItem
After looking at images on TrekCore twice over, I can't seem to locate Patrick Stewart wearing this costume. He wears one white costume (which is different) and a green costume. Rather, he wears this in "Lessons" and "Attached". (Thanks Jorg!)
STAR TREK: TNG “RIKER DISGUISED AS MALCONIAN"
http://cgi.ebay.com/STAR-TREK-TNG-RIKER-DI...1QQcmdZViewItem
The species name is actually 'Malcorian'.
STAR TREK: VOYAGER "FURY - MOLD OF 'AGED KES'"
http://cgi.ebay.com/STAR-TREK-VOYAGER-FURY...1QQcmdZViewItem
The mold incorrectly states 'Kas' instead of Kes.
STAR TREK: VOYAGER "KES'S QUARTERS - OCOMPAN BUST"
http://cgi.ebay.com/STAR-TREK-VOYAGER-KESS...1QQcmdZViewItem
The bust was first seen in "Warlord", then "Worst case scenario", followed by "The gift" and finally once more in "Fury".

Cheers!
