Unless you were expecting someone to do your homework for you.

i) Registers[season,Title,…]
ii) Showing[Time, Date,…]
iii) Stay/Visit[StartDate, Duration]

Taking the first one.
You have a Player.
That Player can play in many Games.
In addition each Game can have many Players.
That's your many-to-many association.

The association class in between is a mapping between a single Player and a single Game.
So it needs attributes that allow it to identify which Player and which Game.

Ok so i could call this class Plays

with attributes like playerName and nameOfGame?

would this be ok?

That looks about right to me.
