I'm not quite sure whether the last photo includes all 6 of them but using the third photo they are from left to right:
1. Akizuki Mika (秋月三佳)
2. Asakura Yuma (朝倉由舞)
3. Momo Shiina (椎名もも)
4. Konno Anna (今野杏南)
5. Fujisaki Arisa (藤嵜亜莉沙)
6. Iriya Mai (入失麻衣)
And i think these are from WPB-net February 2012 edition
