Need Ideas for wiring cord lights

I am planning on changing out my home office lighting from a single pendant light that came in the house to a multi cord lighting fixture. I plan on having 6 lights total and would like them all wired to the same fixture box. I am stuck on how to wire this correctly. I have been told I can wrap all wires together (hot with hot, neutral with neutral, etc.) but also came a crossed the idea of using a 6 pole terminal box. Input on the correct way of doing this would be great.
And if I do use the terminal box, how do i wire the ground wire from all lights?

Any help appreciated, below is an image of what I'm aiming for except with 6 lights (5 going in multiple directions and 6th hanging straight down from ceiling canopy) and also a diagram of how i plan to have them set up.

 

Connect all of the ground wires entering the box together.

For a metal box, add a short jumper wire (a pigtail) from the ground wire cluster to the box. This screw should do nothing else besides hold the ground pigtail on the box.

If all of the wires in one cluster don't fit in one wire nut, you can divide them up and use more than one wire nut with pigtails connecting the clusters.

 

If the individual cords to each lamp do not have a third conductor for grounding then nothing in those cords would be connected to the ground wire that came from the feed cable into the ceiling box.

 

Due to the amount of wires that would be bunched, i would assume it would be a jumbled mess. The ground wires i could deal with, but as for the other 12 ( 6 hot, 6 neutral) what would be the best wiring method? I've looked at terminal blocks or even push wire connectors. If anything just to keep the wiring job clean and not jumbled looking. would this work?

 

Something like this perhaps?
