They are the girls to the immediate right of Nodoka (瀧エリ then あかね). Their names are known because they appeared in the closed captioning in the first episode, and Eri's family name is known because she appears on the class listing in that episode (Akane's is still unknown, I think...)
There are 38 students in Class 3-2, but only 35 shown in this picture. Apparently, in the video release, KyoAni added three more students on both ends of the front row. The students not shown here are Kimura_Fumie, Sasaki_Youko and Mihara_Kazuko.
I would love to see some Wakaouji Ichigo and Kinoshita Shizuka fanart. Ichigo cause she's awesomely never smiles and Shizuka cause the few scenes she's in, she's cute.
