So you only need 1 (correctly sized) capacitor for all the servos as long as they are all connected to the same voltage source. That voltage source should not be the arduino for that many motors. When the motors start pulling too much current, the voltage necessary drops because the power is constant.
Adding a separate capacitor for each of your servos will make them get constant voltage, even if the voltage before the capacitor drops due to increased current on the common wire – each servo will have its own small “reserve tank” of electricity to fill the gaps. Second is induction. Wires are basically straightened coils.
So the max current will be 2A in total. You will need low value ceramic capacitors in parallel with the large value capacitors so that high frequency noise is suppressed as well as the low frequency stuff. Favourite is to use a 0.1uF ceramic capacitor across a 470uF to 1000uF capacitor for each servo.
The reason why you want a separate capacitor near each of the servos, instead of one big one, is that when the load on wires is changing, the wires themselves also become an electric element – they become a coil.
Motors need their own connection to the power supply. That is a large and power-hungry servo. You need a separate supply that can deliver at least 2A, preferably at 6V or more. The Arduino 5V regulator is good for about 0.2A. A capacitor isn't going to be nearly enough help.
As per the Inmoov website, you need to feed the servos via a separate 5-6V power supply. No caps required. You need a seperate power supply of 5/6 V for the servo motors. Otherwise you will see jittering in them as they receive noise from the board and it struggles to power them. You won't know if they need it or not until they are loaded up.

I''m back with a question on how to use diodes and capacitors on servos. I''m using the Arduino Due board to process sensor information and send out mapped degrees to servos.

Get yourself a electrolytic capacitor with the appropriate voltage and a capacitance of anywhere between 100u and 500u, place it between V+ and GND close to the servo. Be advised, these kind of caps are polarized, so place it correctly. Yes you can. Depending on the current and break time the capacitor MAY need to be large.

Servo and Capacitor
A capacitor can sometimes help with a regular DC motor because they need extra current when they first start rotating. A servo has different characteristics. If you are powering through the Arduino, using it''s on-board 5V regulator, that can''t supply enough current to power a motor. Motors need their own connection to the power supply.

A servo motor draws a substantial current in short peaks. And USB power is not designed to provide such current peaks (and the cable makes it worse), hence the current peaks cause the voltage to vary, which the Arduino is not designed for.
