It should be enough to say which algorithms you use and the order. It looks like you've picked common enough ones that they shouldn't be lost to history. I'm slightly more worried about encoding and the wire format of the various bits of data stored in the QR codes. You'd need slightly more detail than just the algorithms used. For the record, the entire design is actually outlined here[1] in lots of detail so really all that would be necessary would be encode that document as a PDF you can print and store with the backups.
