Resources for wire management?

From what I found yesterday, the connector's world is of Jupiterian dimension.

The various connector;s names are a matter of inspiration, as far I could see in the hardware stores. Could be some standard names, I do not know - Thank you for any resource - glossary!

In the attached photo you can see the most interesting ones I brought.

Notes:
a) the "morsettes" - individual 2 ends connectors, linked together in stripes - looks very versatile, like an unidimensional breadboard
b) the bus bars - 2 types: double and simple - heavy but easy to mount by screws
c) the very small: i. 4+1 push-in (permanent) and ii. 4+1 lever-operated - these are impossible to mount - I am planning to tinker them.

The wire nuts I did not find on site, I have to order them on-line.
