is it safe to supply an arduino joystick with 6 volts of power with 4 AA batteries instead of 4.5volts from 3 AA? will that 1 extra volt damage the joystick?
Don't know which hardware you are referring to, but generally 6V into a 5V circuit guarantees crying.

I would be more concerned about putting the 6V out on the wiper when it's fully over to the high side, into an Arduino analog pin, if that's what you're planning.
Just put two or three 1N400x diodes in series with the battery V+ and a 10k pulldown resistor and that will give you roughly 5V. Otherwise send the output from the 5V regulator on the Arduino Board and run 6 AA batteries into the power input. That is if you are indeed planning on using this with an Arduino.
As in the previous post I'd be more worried about the Arduino Inputs than the voltage across the Pots in the Joystick if this is a straight up analog Joystick.
what about 5.2 volts?
Can you show your circuit diagram ?
6 V would be high for an arduino input.
Use of a resistor and zener may be appropriate.
Voltage to input above the supply voltage of the arduino is a rather bad idea.

i just have a power bank directly inserted to the bus,i just used a multi meter and it says 5.15 volts. how and were doi add a diode and resistor to decrease the power?
Are you using this Joystick with an Arduino. If so why don't you Power it from the 5V Out on the Arduino itself.
If not put a diode in series with the positive of the battery. Anode to V+ and Cathode to the Vin on the Joystick board.
