If air is let into the brake fluid at a brake calliper, will this affect the whole brake system or will it only affect the calliper where the air is near it? I'm very sorry for my ignorance, but it would be greatly appreciated if someone could help me.

Can potentially effect the complete system.
I would suggest that the complete system is bled in the correct sequence

I would suggest the opposite. I know that's not helpful. But if all you've done is swapped over one calliper then it is possible to bleed just one calliper. Can depend on the design of your system but most cars have an individual line to each wheel so any air bubbles generated from calliper replacement would have to travel a long way to start effecting other parts of the system. In the garage if we change a calliper over we would only bleed the wheel where the repair was carried out.
Having said all of above... it really does not hurt to bleed the whole system. BMW recommend you do this every 2 years anyway, so all our customers have their brake fluid bled when due and they get a stamp in the space in the service book to show it has been done.
