Yes, they are in a class of software called "decompilers". You need one which can handle the specific target architecture and language variant in which you're interested. However, you need to be pretty darn good with hex, assembler, and C to decide which one you need, how to use it, and how to read the output. There is a good chance that a decompilation suite for the specific job you have in mind does not exist, although a generic one might get you close.
What exactly are you trying to do? It would probably be simpler just to write your own code.
Not much you can do, except ask the maker for their source code. If you're trying to steal their code, then they're probably going to say no. How did you get hex files that you have no source code to?

What is your country? Can you give a link to the magazine website? Did you download the HEX file from the website or did it come on CD with the magazine?
Well you're going to have to learn assembly, I've never seen a hex file converted (disassembled) to anything except uncommented assembly. To make matters worse if the original was in C or some other high level language the disassembly version will be cryptic.

This is true. The disassembler (or decompiler) has to create its own symbol names etc. and unless you are handy with assembly it'll look like digital porridge.
Reverse-engineering is something which takes practice. I used to do it quite a bit on Intel boxes but I'm rusty. I used lots of notes on paper to keep track of what was going on. I've never tried it from a HEX file.
