Spoiler for Index LN:

If Seria is Touma's childhood friend and knew Misaki before as well as the existence of rivalry between her and Misaki, then Misaki may have met Touma during the childhood time, elementary school I think. But in post-childhood time, on the other hand, it's unclear if she still having a relationship with him at that time being.

Speaking of memory loss, I think she's aware of it most of the time since Daihaisei. Or did she already knew it? Let's just say that she might have visited Touma in hospital and learned that Touma has suffered memory losses through Heaven Canceller before Index came to the hospital and see Touma. Pretend Misaki knew that Touma has 'amnesia'.

I'm not sure she thinks he has amensia until NT 7'ish...
