I am not sure if I understand "fading steps" correctly. Usually I'd say
that the single step is there as long as there is any kind of riser (in
German the term is "Steigung", see http://www.vbg.de/apl/zh/z113/8.gif for
reference). I imagine you intend with "fading" that the riser will get
smaller along the single step until it reaches zero. That zero point is the
end of the stairs and if these ends of the single steps of one stair are
not in a line you'll have to model also a "lateral" way (typically they are
in line).

I think the easiest way to represent several upper and lower is to model
several stairs, one for each upper+lower combo. This can happen for example
when there are blocks in the middle of the stairs.

Here is a reference picture of one of the most famous stairs outdoors:
To model the lower main part (between the lateral walls and until the 2
dominant street lights) you'll need 9 relations: 3 times (left, middle,
right) 3 parts of stairs (the former divided by 2 landings). I suggest to
model the landings as highway=pedestrian, area=yes.
