Lee, 
Probably all of the above-mentioned have the capability of being
potential pollenators - *IF* pollen-shed/nutlet receptivity patterns are
compatible - and this will vary from cultivar to cultivar.  I can't
say for sure if a single buartnut would be self-fertile, but certainly if
one or more potential pollenators are present, the likelihood of getting
good nut crops would be enhanced.  
Typically, I would anticipate the buartnut, butternut, heartnut, or
Japanese walnut to be your best bet for getting the job done, but there
are some confirmed buartXblack trees out there, so cross-pollenation with
J.nigra does occur on occasion, even without human intervention.
