How will this woofer perform in a .6 cu ft box ?
It will perform well in a sealed .6 cu ft. enclosure with a F3 of 58.2 Hz.

What si the ebst box size for four of these woofers in a single box? According to the specs a ported enclosure recommends around 5.5 cubic feet and that's pretty huge.I was thinking more around 3-4 cubic feet @ 40Hz.
The parameters of this woofer call for a very large ported box. If you put it in a smaller box you will have a very large peak in the bass response which can cause a boomy sound, as well as severely limit the bottom end below the peak. These will really work best in a sealed enclosure providing a smoother response and more extension capability. 3-4 cubic feet for four woofers sealed would be ideal and will reach ~40 Hz without a problem.

How would these work in an Acoustic Research AR-18b? (.34 cubic feet, sealed, 2000 hz crossover 88db sensitivity.) Would the paper GRS 8PF-8 be better? Or some other 8" woofer?
Either option will work well in that speaker. The rubber surround on this model will last much longer than the foam of the other however.

How does this unit preform when ported?
With the very high Qts this will have a large bump around F3 which can be undesirable. It will act as a natural bass boost, so if you like the bass turned up or loudness button pressed you may like how it sounds.

Would this woofer be a good replacement for a pioneer model CS 44 ?
This might be a good option. The main thing to check would be the actual driver dimensions. There is some variation on speaker frames so the outside diameter and cutout is important
