Answer: 
An inode is basically the data sitting in one of more files (it's actually an index into a table of some sort with which you can locate that data).

A file, on the other hand, is a directory entry that points to the inode.

This is how UNIX-like operating systems implement hard links, the ability for two files to be "equivalent", so that changing one will change the other. Since inodes are unique per file system, you can have more than one file referencing the same data (as long as it's on the same file system, of course).
An inode is on-disk metadata that represents a file. It contains the file's permission bits, the creation/modification/access timestamps, the actual file type, size of the file, etc...

A "open file" is simply a bit of memory in your process. Generally it's an array entry, which the filehandle you get from fopen() calls is the specific array key of. That array entry will contain (among other things) the current location of the cursor in the file where you'd be reading/write data from using the fwrite/fread calls.
