How to register this game

I know may be this is a stupid question, but I really got confused.
my gal friend want play this also, so I have invite her in the game, she has a SamSung Android phone, and she has installed this game, she also got the invate mail from haypi.com, but we really don't know how to may her registered. if she tap "login" she will be gave a random name ha_xxxxxx, and if she tap account, she has no usename and password available. how could she registered this game.

And, Can she also join same server with me?

Have her complete task 4 and collect the reward, then a task 5 will appear allowing her to choose a name, password, etc

And not at this time

if you wait till you are both level 10 then create accounts at the same time then you are likely to be placed on the same server

Doesn't it cost 10 coins?
