I have an I phone 5 that i would like to use but it says the password or apple ID is incorrect how can I up clear this ?

Without the correct Apple ID and password, Apple devices are usually useless. The activation lock prevents people from using stolen devices.

If you have the original sales receipt with the phone's serial number and proof that you are the owner, Apple may be able to help directly.
