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).
