.swf

Sever? Don't you mean server? An .exe file is a Windows executable and will not run on your Mac.

Here is what we know so far. You have a bunch of unnamed .swf files from an unnamed source. You also have an unnamed server application whose functionality is unclear.

It seems to this reader that the gaves are in .swf format because that format requires no built-in executable code. You should be able to run your games from within any web browser that has a Shockwave plug-in installed. As for your mysterious Windows server, I am at a complete and total loss as to what functionality it could possibly provide.

My advice to you is to install Shockwave on your Mac and then to open the game files in your browser.
