I'm no expert but from what i have learned, here are my simple answers:

1- basic
2- more K even though boths in the #1 has provided
3- MGSO4 is added if you tap water is low in magnesium
4- 2 and 3

I have #2 with CSM +B and Fe (10%). I have no idea if i need MG or not but so far i don't see any problem. From my point of understanding, EI method is you dose more than what the plants need then reset the whole thing with huge water change. You don't look at the algae or the amount of ferts needed to be dosed ( not what type) but you need to look at co2, light and plant health. Basically, again in my own point of view, use EI and you ignore everything but co2, light and plants health.

Hi its Nam =D

KNO3
KH2PO4
Plantex CSM +B

Unless tap water GH is quite high, enough GH booster to raise GH 1-2 degrees.

I use:

Gh booster
KNO3
Plantex mixed with DTPA and Fe Gluconate: 4:1:1
KH2PO4

Note, most all basic fert routines add the same things, they just add them at different amounts, so adding more of one, is the same as adding another. DIY fert dosing came from PMDD back in 1994/5, so all can be traced to that routine.
EI is basically 90% PMDD but tosses the test kit part out, no one ever does it anyway, even if you nag nag nag. Ups the water changes and makes ferts independent. If you want optimize the dosing, then you slowly taper off till you note any change in the growth(called the critical point) IF......the tank is doing very well...........if the tank is not doing well to start with, well.......then it cannot be independent, you have other issues unrelated to ferts.

By tapering off and observing, you can then reduce the % water changes, or not. It's up you there. I garden heavily in some tanks, so I do more Water changes, others, not much at all, so I do few in those(2x a week vs 1x a month).

A pretty wide range.

Tom Barr
