LOL The only two I could just tell apart were Hyoyeon and Sooyoung, and even then I sometimes looked at Hyo like 'Wait, who's that?'. Hahaha. I had to recognize them in pairs first, then individually. XD

omg I was in the same boat .. I got into the girls during Gee era and after watching the mv 3892374 times I thought I knew everyone already .. Then the first Genie promo pics came out and almost all the girls got different hairstyles .. I just wanted to scream in frustration

When it comes to the vocals Hyo, Jess and Sunny have the most distinctive voices and Yoona has the most bland one imo .. I can tell everyone apart now though .. The thousands of plays were worth it XDD

If you wanna get more familiar with them I suggest you watch their variety shows, like Girls Go to School, Hello Baby, Horror Movie Factory ..etc. Or when they guest on shows like Intimate Note (HIGHLY RECOMMENDED), Win Win (hosted by Taeyeon), Happy Together and Come to Play.
