Unfortunately I can't help with p_noriko, since I never bothered to collect her first set and it's not among minisuka's online archives. Let's see if we can get the rest figured out though. I also post the number of pictures per set, because there used to be many incomplete versions available on the interwebs. I did not include the small making-of clips that are available for each set.
p_noriko2 should have 10 sets
p_noriko2_01 = 46 Pictures
p_noriko2_02 = 60 Pictures
p_noriko2_03 = 53 Pictures
p_noriko2_04 = 50 Pictures
p_noriko2_05 = 65 Pictures
p_noriko2_06 = 55 Pictures
p_noriko2_07 = 46 Pictures
p_noriko2_08 = 43 Pictures
p_noriko2_09 = 46 Pictures
p_noriko2_10 = 46 Pictures
p_noriko3 should have 11 sets (=p_noriko3_st1)
p_noriko3_01 = 50 Pictures
p_noriko3_02 = 43 Pictures
p_noriko3_03 = 60 Pictures
p_noriko3_04 = 40 Pictures
p_noriko3_05 = 40 Pictures
p_noriko3_06 = 45 Pictures
p_noriko3_07 = 51 Pictures
p_noriko3_08 = 38 Pictures
p_noriko3_09 = 40 Pictures
p_noriko3_10 = 32 Pictures
p_noriko3_11 = 48 Pictures
p_noriko4 should have 8 sets
p_noriko4_st1 should have 6 sets, but the pictures are the same as p_noriko4 only that 2 sets weren't split. Details below.
p_noriko4_st1_01 = 64 Pictures (=p_noriko4_01)
p_noriko4_st1_02 = 43 Pictures (=p_noriko4_02)
p_noriko4_st1_03 = 81 Pictures (=p_noriko4_03+07)
p_noriko4_03 = 52 Pictures
p_noriko4_07 = 29 Pictures
p_noriko4_st1_04 = 61 Pictures (=p_noriko4_04+08)
p_noriko4_04 = 32 Pictures
p_noriko4_08 = 29 Pictures
p_noriko4_st1_05 = 42 Pictures (=p_noriko4_05)
p_noriko4_st1_06 = 47 Pictures (=p_noriko4_06)
p_noriko5 should have 6 sets (=p_noriko5_st1)
p_noriko5_st1_01 = 33 Pictures (=p_noriko5_01)
p_noriko5_st1_02 = 32 Pictures (=p_noriko5_02)
p_noriko5_st1_03 = 38 Pictures (=p_noriko5_03)
p_noriko5_st1_04 = 41 Pictures (=p_noriko5_04)
p_noriko5_st1_05 = 40 Pictures (=p_noriko5_05)
p_noriko5_st1_06 = 33 Pictures (=p_noriko5_06)
p_noriko6 should have 5 sets
It's not in the archives yet (so no p_noriko6_st1 yet), so I can only tell you what I have. Maybe it's complete, maybe not.
p_noriko6_01 = 35 Pictures
p_noriko6_02 = 35 Pictures
p_noriko6_03 = 50 Pictures
p_noriko6_04 = 55 Pictures
p_noriko6_05 = 27 Pictures
