I2c protocol

hello every one thanks for begin together.
sorry for my bad English...

You have four Ardduino UNOs -- UNO1 to UNO4; where, each Arduino is connected with I2C sensors. What are these sensor?

You have another Arduino UNO (the UNO5) which collects data from the above four UNOs. Correct? What will UNO5 do with these data?

After I have prepared the code to read a set of data and convert it to Char and all of them with a matrix to send it to another Arduino through the I2C protocol how can I read it individually and control it.

here is the code

after i receive data from the 4 uno i will on some alert in uno5 witch coolect data and through buzzer during the read of the data
sensor i used temp,humidity,presser,some logic switch
