to do a side by side comparison test is a scientific job.
I tried my best
D800 on tripod
use flash light
1/200s
around 1m focus distance
I use manual tuning focus adjustment on D800 liveview, but still for the full open aperture, any 0.5degree angle difference could conduct different results.
so this is just for you referance

Looks like the 50/2 exhibits more vignetting but I'm puzzled by the long nose comparison: latter exhibits some LoCA (green cast on left clock minute markings) : was the focus set adequately, or is the clock behind the focus plane?

the comparison picture is part of the full photo, I aleady gave the full photo scene.
the focus point was on SS plate piece, the center of the bigger timer

for the Round-2 test, for the copy I had and the test conditions
what I observed are:
AI 50/2 is a little lower contrast compare with Ai/AIS 50/1.8 @f2, and it makes the Ai/AIS 50/1.8 longnose looks a little sharper
but 50/2 wins in the image quality of extrme corner
AIS 50/1.8 japanese pancake version(full metal) @f2 is worse compare with 50/2
Ai 50/1.8 longnose is almost identical with AiS 50/1.8 longnose at f2
Micro-nikkor 55/2.8 is better than AF-D micro-nikkor 60/2.8 when full open, surprised me!
final funny one
Micro-nikkor 55mm f2.8 vs Russian Industal 61 L/M MC at f2.8
Industal-61 is Tessar optic structure, I was love this small lens very much until I met the Micro-Nikkor 50/2.8 "eagle eyes", from today's test, we can see 55/2.8 is really sharp even fully open

That is not surprising - these lenses have the same optical design.
Your tests also confirm what I have long suspected - the longnose 50/1.8 is one of the best manual focus standard lenses that Nikon have made, definitely better than the more compact versions which followed.
I have never tried the AF-S 50/1.8, but I heard this is also a very good lens (it has an aspherical element, probably hybrid plastic molded onto glass), but it has higher distortion.

af-s 50/1.8 is larger and plastical， so I don't have a copy and interest ;D
I also had a sigma 50/1.4 art ，this is not same level player.
I think for hobby. The full open aperture performance of these 50/1.8/2 is already good enough.

The old Micro-Nikkor 55mm f/2.8 is hard to beat in a setup like the one you did. It's a very nice universal lens only drawbacks, in some situations, are relatively long focus throw and light gathering.

as a universal lens , the drawback of this 55/2.8 is the very short focus throw from 2m-infinity,which easy to miss the target in focus.
what surprised me is that 55/2.8 actually is old but is also not a very old lens, Nikon stop the production at 2020 (1979-2020 according to http://www.photosynthesis.co.nz/nikon/lenses.html#50slow)

some samples of Ai 50/2
-
I found the Ai 50/2 has better CA compare with nikkor 50/1.8s
-
to me, Ai50/2 is sharp enough when full open

Compared to non-macro lenses like the 50/1.8, the focus throw to the same distance is shorter, but I find it adequate. The focus throw is much longer than that found on the AF and AFS 60mm macro lenses.
The 55/2.8 can suffer from flare when the sun is inside or just outside the frame, but the deeply recessed front element protects it from flare in most situations. The bokeh can be harsh so some care needs to be taken with backgrounds. Otherwise, the 55/2.8 is a very good standard lens. In most cases f/2.8 is fast enough, and the ability to focus closer than normal is very useful. I used this lens a lot when travelling and hiking due to its small size, light weight, good optical properties and versatility.

,,, The focus throw is much longer than that found on the AF and AFS 60mm macro lenses.

Thank you for the confirmation on focus throw!
I use it for Infrared photography as well and I find the Bokeh quite good in most situations.
Flare and especially hotspot pattern is more pronounced in this version f/2.8
The older f/3.5 it's a bit better regarding hot spot and flare resistance in Infrared when stopped down. Must be something to do with the coatings and reflections of the aperture blades since the optical layout is almost identical for most of these versions of the 55mm.

55/2.8 and 55/3.5, they have different optic design
f2.8 is gauss type, and f3.5's rear group is xenotar

personally I think 55/2.8's bokeh is good, not as bad as typical gauss type lens

Main problem areas with the 55/2.8 Micro-Nikkor are firstly, a propensity to get lubrication leaking onto the aperture blades thus making the iris sticky or in worst case, not operating at all; and secondly, it flares badly in some contra light situations, even when visible flare is avoided, there is a pronounced lowering of contrast.
I discarded two defective samples of the 55/2.8 before I got a good one. Bought in Copenhagen by the way, on one of my visits to Erik. Thus the 55/2.8 promptly was CPU-modified and operational a few hours after the purchase :).

yes, I once had one with this issue, and I have to learn how to maintainance ;D
