1) V has the physical ability to jack into a device to decrypt/download/etc data from a device. Is there a physical place he may do that, even if it takes him some time to find?
There is not a physical place for him to get into the ICPs. He might be able to get in peoples own devices (obviously with character plotting)
The rest assumes 1 is yes, if the answer is no then just disregard.
5) Netrunning exists in canon. It functions in a way where you jack in and you basically upload your consciousness to the net and literally traverse the space. Encryption layers are represented as walls, so this is entirely separate from the encryption question. Would this be a viable way to communicate more directly with the train? (V directly communicates with the AI that was once Alt Cunningham while netrunning, for example.)
He wouldn't be able to do this with the train. However there will be opportunities on missions for him to access tech and netrun - so feel free to poke for answers on appropriate worlds.
also I forgot to answer your questions...
