user15688: I am trying to build a project that contains more than one MPU 9250, until now I'm still confused to MPU9250. If I were going to that, does anybody here know how to set addresses to each of the MPU's I am going to use? Thank you for spending time reading my question. I hope someone will help me get through this.

user13432: It is possible to have up to two MPU 9250 devices on an I2C bus without any extra logic. Pin 9 (AD0/SD0) defines the lowest bit in the I2C address of the device. Please see Chap 7.2 I2C Interface 
If you need to connect more than two devices this can be done by connecting the AD0/SD0 pin of each device to a chip select pin on the arduino. This pin is asserted when addressing the device (This solution was provided by @Gerben, see comments below).
An example with three MPU 9250: Arduino D4-D6 are used as chip select pins. MPU1 AD0/SD0 pin connected to D4, MPU2 pin to D5, and MPU3 to D6. D4..D6 are initiate to HIGH. When addressing a MPU the chip select pin is set to LOW and the lower I2C address is used for access. The other MPUs will be listening for the higher I2C address. 
Cheers!
