I don’t see how the rest of the conductors connected from GEC water pipe to grounding electrode in the sketch post #5 are bonding jumpers? Bonding jumpers connect between two metal parts definition of bonding jumper NEC 2014 Section 100.

However in sketch except for intersystem bonding terminal rest of conductors connect grounding electrode to system grounded conductor definition of grounding electrode conductor NEC 2014 section 100. Are they not grounding electrode conductor?

They are all part of the Grounding Electrode System

Yes but note label as bonding jumper in your graphic connect two metal parts steel to pipe, pipe to reinforcement rod, grounding electrode to grounding electrode etc. Also note in your graphic grounding electrode conductor is continuous nothing connected.

In the sketch post #5 conductor is connected to grounding electrode one end (metal) and other end it’s connected to GEC (conductor) which connects to system grounded conductor. How can that conductor be bonding jumper?

You can't be serious.

There is at least one GEC and all the other electrodes get bonded together. It's that simple.

What you seem to want is a paragraph describing every possible connection and every order they can be connected in. Think for yourself man and have a little confidence in your ability.

Its made of copper. I guess you can count the GEC to water pipe as metal post #5 sketch which would then make conductor connection GEC (metal) to grounding electrode (metal) and thus bonding jumper.

It's been explained so we don't need to keep going in an endless circle.
