They seem to be just a regular 52mm circular filters mounted onto a sliding frame.
I'm not sure if the existing filter is removable or not, so I'm wondering—
1) Should I remove the existing filter off the frame and then use whatever filter I want? OR 2) Is the filter non-removable, so I should buy more drop in filters? The selection seems quite limited? OR 3) Does Nikon make a filter holder I can't seem to find anywhere? (I would assume this part is very expensive as well)
My understanding is that the filters are special versions with a thin ring. These have a designation in the description... sorry remote here so I don't recall what it is. The filters I have are POL for the 200-400 and the 400/2.8... they are both the same. I believe you can take the existing clear UV filter out, but if you replace it, it needs to be a thin version of the filter. You may have to look in the manual for the 200-400 to see what it says. When you buy the POL filter, it comes with the holder and the external small thumbwheel to allow you to rotate the filter externally. Hope this helps a bit. T
The filters screw in the holder, so you would unscrew the NC filter and screw the new one into the holder. Just make sure the width of the filter ring is no wider than the included filter or you could get it jammed. There would be no real reason to buy additional filter holders.
The CP filter is part of a special holder that inserts into the slot instead of the standard holder. As mentioned above, this is to enable remote turning of the filter.
I am curious as to what filter are you wanting to use? I don't know many photographers who use non-CP filters in long lenses. I guess a colored one for B&W is an option.
My older AIS telephoto lenses used to come with a second holder where you could cut gels and install filters that way. I have never used them.
I bought a CP with the lens, and have put it in maybe 3 times over several years. I've never had an urge to use other filters, post processing is good enough today for anything but ND and CP and I think you'd need a front filter for graduated ND.
I will say that the included clear filter is in the ring so firmly when I tried to unscrew (just to experiment) I could not break it loose by hand. I did not try any tools (as I did not really need it off), but I've read elsewhere that initially getting it to unscrew can be a challenge on some lenses.
I have an older 500mm F4 AF-1 and a newer 300mm f2.8 AF-S.
The 300mm f2.8 takes 52mm filters and I think your 200-400mm lens will also take 52mm filters.
I suggest that you purchase Nikon filters as these filters are of a "thinner" construction, compared to a "Hoya" for example.
You may find that some filters are too thick to drop into the slot when assembled into to the carrier. Of course, you could go to the trouble (and expense )of having thick filters machined down, but, that is somewhat impractable.
If you are looking for a circular polariser, I feel the Nikon C-PL 1L may be the correct unit. This one fits my 300mm f2.8 AF-S. Best to check first though if you want to purchase one.
Nikon manufacture "drop-in" filters in 39mm and 52mm sizes. The 39mm is for some of the older lenses, such as my 500mm f4 AF-I.
The CL-P1L drop in is the 52mm for the 200-400. I don't know what other filters are available that and the included clear filter are all I have for mine. The clear should always be used (so they say) as the filter is a part of the optic formula for those lenses.
The CL-P1L is different from the clear in that it has a wheel to rotate the filter. If you could fit a standard 52mm filter on the clear holder you would have no way to turn it. I've never tried to remove the existing clear filter from the holder but I don't believe its meant to do so.

I always wondered about that statement, when combined with the big, meniscus "filter" on the front that you can take off or leave without any impact other than reducing some lens flare. But the optically flat filter is somehow relevant.
I leave it in because one is supposed to have a filter to prevent damage to the rear element of the lens.
Yes, the Nikon 200-400 uses regular 52mm filters as long as they are not too thick. I use the B&W 3.0 (10 stop) ND filter to take photos of the sun. Live view and eyepiece closure are advised to save your eyes from UV and IF light than may or may not be coming through the lens even with the filter.
I'm sure I've seen replacement filter holders for the 200-400 but can't find one right now. Don't loose the original.

You don't worry about overheating internally? From my telescope days, I never used anything but a front objective filter, like Thousand Oaks.
