hi i have an phone 4 s and i cant find siri on my phone plz help me!!!!

Go to settings/general ->siri to enable siri.

Are you using IOS 6 and above?

What is the model number of your phone? You can find it in Settings>General>About>Model. Please post what it is.

You posted in the iPad forum instead of the iPhone forum. To get answers to your question, next time post in the proper forum. See https://discussions.apple.com/index.jspa I'll request that Apple relocate your post.
