Hi 72942sham,
>> the syncing process of Office files using OneDriveSync
By this, do you mean the OneDrive for Business or OneDrive for personal? You could refer to
this article to determine which version of OneDrive you are using. If you mean OneDrive for Business, it is recommended to download the poster from the link below to learn about the synchronization steps a file goes through when it passes though OneDrive

>> I came across various exe i.e MSOSYNC.exe, MSOUC.exe, CSISYNCCLIENT.exe etc
Based on my research, these exe files are all part of Microsoft Office Upload Center. Microsoft Office Upload Center give us a way to see the state of files we're uploading to a server, in one location. When we upload a file to a web server, Microsoft first
saves that file locally to the Office Document Cache before it starts the upload, which means that we can save changes and immediately continue working even when we are offline or have a bad network connection. The Microsoft Office Upload Center lets us keep
track of how uploads are progressing, and whether any files need our attention. You could refer to the following link for more information about Microsoft Office Upload Center:

Hope the above information can be helpful.:)
