compilers for languages from 1950's and 1960's

i am trying to find the best compilers (if they are actually available) for the following languages:

i don't know if any of these are still around, but it would be very helpful to get any feedback on where i could locate these.

    Of course, most of the original compilers ran on machines that are no longer in existence, but the museum also has a PDP-8 emulator.
