Answer 2

The more challenges you win at a certain language, the smaller your victory xp gets. Try a language you never used before and you'll get ~31 xp.
This is not a complete answer, but I hope there will be someone else who will help you.

Answer 4

The level doesn't mean.
It about the xp you have in that particular language

I believe it may work according to some elo system.
