Sometimes they have special offers like signing up for their email list and you will get 3 stars. Other than that no.
You cannot earn stars on tap zoo. You need to buy them through the app by paying real money.
You can earn diamonds by finishing certain quests. The reward on these quests are diamonds. Or of course by buying them in the store. (I don't recommend that. It's not worth it. You can go on the game without ever using diamonds.)
You can tap the coin or star sign on the top right hand corner and download apps for free or pay for them
By Buying them :3
simple. you cannot earn treats without overpaying for something.
Near as I can tell you either have to pay real money and buy some or download apps (some free and some cost) and get them that way.
I wish I knew
Buy them from the "store" on the app.
No, you cannot.
Go to the store. Tap games. Download any app. Paid apps earn you more. 100 credits equals 2 songs

It is the story creator. Go to the menu and tap the stars. There is a book icon in the list, for create stories. Just tap it.
