From an academic perspective, I'd say none of them are bandit kingdoms. The one defining feature of a bandit kingdom going back to the first Periphery sourcebook was the "piranha principle", where the small bandit kingdom "piranhas" of the Periphery were able to attack the Great House "sharks" of the Inner Sphere because the Great Houses were so occupied fighting each other that they largely ignored the bandit kingdoms.
Examples #1-#5 may all be Periphery scum to a lesser or greater degree, but unless and until they mount a raid against an Inner Sphere world, they're not bandit kingdoms. (I'd also note that we can probably find examples of #1-#5 happening on various worlds in the Inner Sphere in the canon.) Even if we want to be loose with the definition of "bandit kingdom", these certainly aren't bandit kingdoms with the scale, reach, capability, or prowess of the classic bandit kingdoms like the Circinus Federation, Tortuga Dominion, Oberon Confederation, Greater Valkyrate, or even Star's End Pirates.
Of course, Spheroid prejudices tend to classify all Periphery states as bandit kingdoms, even the largest, most established, and most peaceful (e.g., Outworlds Alliance and Magistracy of Canopus). So to the average Spheroid citizen, examples #1-#5 may all be bandit kingdoms simply because of the geographical location in the Periphery.
And, of course, to the targets/opponents of their coercion (examples #1-3), revolution (example #4), and imperial ambitions (example #5), each of these states will be termed a "bandit kingdom" or whatever appellation generates the most disgust towards these states and the most sympathy for their opponents. (In the real world, the terms "revolutionary" and "terrorist" are often interchangeable, depending on which side you're on.)
Hope this helps... FWIW.
