The original remotes are always the best match between button names and actual functions. But you can buy cheap remotes that will control your DVD changer and Sony, and probably the Westinghouse. For the DVD changer and the receiver, it will probably be necessary to do some programming at the individual button level.
The RCA RCRP05B (said to be $15 at Walgreens, and $20 at Best Buy) or the OneForAll URC-8820N (<$20 at Sears) both will work.
For the changer, use setup code Audio 1763. Some functions will work immediately, but especially changer functions will need to be programmed.
The TV will probably work with TV 0000.
The receiver will work for basic functions with Audio 1058 or 1258. All of the functions numbers are known, so you can program in every function, including discrete ON/OFF, etc.
To see how this would work, here is a table of known SA-HT70 functions, and the 5 digit EFCs that you would enter in and assign to buttons of your choosing. Of course, the more standard functions are already programmed into 1763, but here's the whole list.

9XX Command instructions.
