Cthulhu Wars. The lady is Asenath Waite. She might be a kickstarter exclusive so might take some tracking down. (Slightly embarrasingly, while they're also CW, I don't know the others, even though I have them in a box somewhere.)
I haven't checked recently, but Fenris, who sculpted it all, were meant to be selling resin versions of everything at some point.

Asenath Waite was indeed a 2013 Kickstarter exclusive.
The other models came from different expansions to the base game. Your photo shows them in maroon plastic, which was the colour of the collector's miniatures that were sent as stretch goals, just about one of each medium and small mini from CW was made as an extra in maroon plastic for the stretch goal called the collector's set.
Apart from E-bay etc, the other miniatures can be found in plastic as part of various sets in two kickstarters from Petersen Games.
Cthulhu Wars Onslaught 2: Late Backers can order sets.
Cthulhu Mythos for Pathfinder by Petersen Games. Kickstarter underway with 16 days left.
The Cthulhu Wars Onslaught 2 are boardgame expansions, so you find the miniatures grouped for boardgame play and can get some cards and counters that work with that game in the set.
The Pathfinder sets are meant to create RPG encounter groups, so may line up well with miniature skirmish gamer's scenarios.
The sculpts by their CW names are left to right:
Wizard - from CW's The Sleeper Faction Expansion, for the Pathfinder kickstarter it is being named and designed with a high level backer.
Abomination - from CW's Opener of the Way Faction Expansion, for the Pathfinder it is part of the Former Human Horrors Campaign Collection.
Asneath Waite - Exclusive First Player Marker from first CW kickstarter.
Ghast - from CW's Dreamlands Underworld Monsters Expansion, for Pathfinder it is part of both the Dwellers of the Dreamlands Campaign Collection and the Mythos Ghast Horde Pack.
Mutant - from CW's Opener of the Way Faction Expansion, for the Pathfinder it is part of both the Former Human Horrors Campaign Collection and the Mutant Horde Pack.
