Yes, of course. But you realize, that it's 99.9% unlikely that
you'll be allowed to export the source code, right?

No idea about CAST, probably it's too good for it.
Yes for CDMF (IBM-patented, clever reducing the key strength
to 40 bits, as opposite to simply accepting a 40-bit
key only from a user).
Yes for RC4 (legal status unknown to me. The last I heard,
RSADSI believes it's their property and would
like you to pay for the license).
Yes for RC2 (same as RC4).
There is no "DES-40" per se, unless you mean CDMF; to the best
of my knowledge.
I'm not aware of any other crypto-algorithm that has expedited
export approval (which doesn't guarantee you'll be allowed to
export - simply that "Yes" or "No" will be given within three
weeks or so).
