Please Help! In George Orwell’s ‘animal Farm’…?

I read the book for A.P. World History, but I was so confused, couldn’t understand anything…so could you please please please help me with some of this? I’ll love you FOREVER!
In the book, identify who or what each of the following represent:
The Manor Farm (I thought this was Russia…but could it have been Europe?)
Old Major
Snowball
Napoleon
The puppies
The Dogs
Mr. Jones (is this Lenin, or Czar Nicholas, or…?)
The Animal Rebellion (the Bolshevik Rebellion?)
The Battle of the Cowshed
Boxer & Clover
Mollie
The Seven Commandments
‘Beasts of England’ (the song)
The flag
The burning of the harnesses
The humans
The windmill
Animalism
Squealer
The eggs/windfall apples/milk/grain
Moses the Raven
The neighboring farms (is this the rest of Europe if Manor Farm is Russia?)
The wild animals
The exile of Snowball (so is this when Czar Nicholas was sent to Siberia? Is Snowball the Czar?)
The locked granary
The rats
Napoleon & Snowball’s respective speeches
The plans for the windmill & electricity generation
The deal between Animal Farm and the neighboring farms
The chickens & ducks
The commemoration of the Battle of the Cowshed
The deaths of the sheep & chickens
Boxer’s death
The donkey
The transformation of the pigs
