Welcome Phil 
The MnM and the A4 have different architectures, so understanding the A4 will not always help you with the MnM, and (as you are discovering) may even confuse you. I’ll try to help, but have you searched for a translation of the MnM manual in your language?
#1
This is simply the way the MnM is organized. You can easily copy one of the 6 tracks from one kit and paste it into another, then save it to a new location. Tedious compared to the A4, I know.
#2
Each of the MnM’s tracks has a dedicated delay. However, effects such as reverb, phaser, flanger and ring mod are available as “effects tracks”, which you must assign to another one of the MnM’s 6 tracks in the kit edit menu. The easiest way is to assign this new track’s input to “Neighbor”, which means the effect will apply to the previous track. So put your patch on track 1 and the reverb on track 2, for example.
(There are more complex routing options available with the MnM’s bus system, which is part of the Mnm’s flexibility and power. But to keep your life simple for now, start with Neighbor assignment.)
#3
As I said in answer #1, you have to save each voice (or patch) as a track to a kit, which again has 5 other tracks. If you like poly mode, one approach that might help you is to gather 6 different voices that you like playing in poly, save all of them as a single kit, then put the MnM in poly mode. You can select the track you want (at far right) and whichever you choose, the MnM will play that patch in poly.
#4
You need to trig the track that is listening to the inputs. It should be an effect track (Thru, Reverb, etc.). At first, check the Amp page and set the Hold, Dec and Rel to 127 (so the gate never closes), and place a trig on the first step of your sequencer pattern. Press play on the MnM and you should hear your synth.
Hope this helps.
