1.) If you are referring to the Android OS, then in general, there is no difference. The devices may come from the vendor loaded with different apps and configured with more or less restrictions though.
2 and 3.) Many apps will run on most versions of Android, but some will only run properly on older or newer versions, and the developer will typically specify which. For example, only some apps will be available on Play Store for certain devices. Depending on how the apps are built, you may be able to side load and run apps on other devices regardless, but the apps may not behave on certain devices and/or with certain Android versions. Some apps are designed to use features that are only available in newer versions. Some apps perform functions that were only useful or valid on older versions.
4.) Current versions of the Android OS use EXT4 for internal filesystems, which will support file sizes up to ~16 TB, though I've never heard of an Android device with that much internal storage. Any limits on PDF files would be imposed by the apps, such as Adobe Reader, Kindle, etc. I am not aware of limits preventing access of 60 MB files, but you would have to determine that app by app.
5.) It depends on whether a developer community exists for any given device, and whether they have decided to port newer versions of Android to older devices. Otherwise you can only update to the level that the device vendor supports.
6.) Play Store is only available to tablets that meet the Google Android requirements, and are so certified. Google Play is the safest and most reliable repository of Android software.
7.) Stok firmware contains the vendor's version of the Android OS. You can load custom versions of the Android OS that were not provided by the device vendor, and those firmware images are not considered "stock."
