At least the ammonium fluoride (I assume you mean ammonium bifouoride), w hich is used in a very dilute solution as a disinfectant in home/off ice fish tanks, has caused fatailties in children when a concentrated sol ution has been ingested. The poisoing seems to be the same as hydro gen fluoride/hydrofluoric acid poisoning, and what data are available indicate that the medical treatment should be the same.
Boron trifluoride (BF3) seems to act similarly to hydrogen fluoride.
I'd have to research the other 3 compounds you list. Perhaps someon e else on the listserve is more familiar with them.

Does anyone know if aqueous solutions of the follow ing fluorine containing reagents pose an HF hazard risk?
phosphate - (mildly acidic solution, pH ~6)
Ammonium hexafluoroalumi nate - (mildly acidic solution, pH ~6)
Ammonium tetrafluorob orate - (mildly acidic solution, pH ~6)
