Please can someone explain to me these errors and possible solution as well.

You have an interrupt conflict. Without seeing your code we will not be able to help.
See also https://bitbucket.org/teckel12/arduino-new-ping/wiki/Home#!multiple-definition-of-_vector_7-error ; if you don't come right post your code using code tags as described in How to get the best out of this forum .
// Edit
Thank you much for replying. I'm using ultrasonic sensor and buzzer and I found out when I remove the code for buzzer the error is gone, maybe that is where the conflict occur?? Im using arduino uno.
Using the tone library? The teckel12 link that I provided gives some possible alternatives to the tone library.

Oh base on the link you gave, both NewPing and tone library used timer2. But I didnt use any library for the buzzer, though I used NewPing lib for ultrasonic.
