I've used all those films Tech Pan was indeed a marvel but really hard work in the darkroom:
If you exposed it at say 40-50EI and developed it in low dilution HC110 results could be brutal:
An interesting film is the infra red is it the B&W or colour? The B&W had wonderful halation, that is the highlights would soften and the grain was quite pronounced.
The colour IR was great too:
Both of these films should be handled in darkness, some load them in a dark bag, although I'd still give it a try as my first roll I didn't do this and it looked OK.
APX is my favourite film of all, the 25 was like Kodak TP in resolution (well almost) but has a wonderful smooth tonal range as did the 100 APX which for Portraits looked quite wonderful.
I have quite a few rolls of both the 25 and the 100APX all dated about 2001-2005 still seem OK despite that.
Enjoy your films you have an interesting collection there.
Have fun!!
