Masah on socks

Q: Can you please let me know can I wipe (masah) over normal socks? Not leather one's because im in Kuwait here most of the people do this. If it's not permissible, can I perform namaz behind them or should I perform individually? Please give me a clear answer.

Masah of the head

Q: I am asking that not long ago I found out that while doing wudu at the end when you do masah, I used to wash my ears first then wash my hair couple of times and I found out the real order and started doing it like the order you really should. So I'm asking that I'm not sure what's the ruling on that because some people say it's okay if you didn't know but now I'm sending this question to you because I really want to know?
