Glows are super cheap so it ain't worth my time to put used ones back in after testing, it's more of a 'aha, that was my problem' type thing. In my case, it was a very dramatic change, new glows are on my September pre-winterizing list now.

Don't fergit the anti-seize.
True, and I am in the different strokes

I can remove and replace all my glow plugs.....with out disconnecting or removing anything...

The less I remove, the better....I have really bad arthritis too.....bending over and I get stuck.....legs start twitching and its not to pleasant.....valve adjustments are not very fun for me.....yes, I have been blessed to have a rare forum, that less then 2% of the population has.....makes me feel special

Regardless of which method is used for removing and servicing glowplugs, I'd like to figure out if the results of my tests/measurements point to a healthy glow system or not.

Money is tight, so I'd rather not replace all the glowplugs if I didn't need to. That money could be spent on a new battery OR perhaps on new injector nozzles if dirty injectors are my problem (too much soot in the chambers?)...

Power the glow plugs with the battery and observe the glow. If it gets yellow red hot at the tip it's good. I use glow plugs till they burn out, that's the time I replace them

If Money is really tight and you have time to go to the Junk Yard with your Multimeter you can get a handfull of used Glow Plugs for the price of One Glow Plug.

Are mine in need of replacing, in your opinion?

No, since they all glow properly, and the voltage of 10 v across then is within limits. I'd ream glow plug holes, adj valves, make sure fuel and air filters are not restricted, tank is venting properly, and if all that does not help, do a compression test.

You need good compression, fuel and air to start a diesel

I did ream the glowplug holes when I took them out to test. As I posted above, glowplug tips were all soot-covered when I pulled them out, and I reamed out a LOT of carbon cake from those holes.

I guess I'll plan on doing a valve adjustment sometime soon and replace the fuel filters.

Can a compression test be done through glowplug holes? I don't have equipment for compression testing, but what would low compression tell me? Is there anything I could do about it anyway?

A light dry soot on glow plugs is ok, heavy or wet soot is not.

Harbor freight has a kit for compression via glow plug and inj holes. Quality is iffy. If you're lucky you get one that do not leak.
