1. Does the Imperial Guard follow a set formation such as: Crusade/Army Group, Army, Corps, Division, Brigade then finally Regiment?
It probably depends on the situation. I think generally "Regiment" is as big as it gets for any single, permanent field unit. But "Regiment" can mean different things/size depending on the type (infantry, armour, artillery, cavalry, drop, mechanised, etc) and also it'll depend on where it's from - which world it was raised on, to the point where you can pretty much make anything work for your particular needs. In general though, the Departmento Munitorum will appoint/elect Generals to lead larger forces which will be made up a load of different Regiments, which is where your Divisions/Army Groups/etc will come into it.
2. Do certain worlds retain an element of control over their tithed regiments? For example, are regiments from one world permitted to fight together in a Corps or Division level in a fashion similar to the DKoK, Vostroyan Firstborn or the Saturnine Fleet.
I don't think the world of origin retains any control or command over its tithed troops, no. Once they're shipped out they belong to the Departmento Munitorum, to be assigned and used as they see fit in service to the Emperor. Of course, multiple Regiments raised for the same mustering can be shipped off together and deployed together, sure. However, Regiments can be split up, merged, dissolved, etc... again as the
DM sees fit. When it comes down to it the fluff is fairly flexible and you're free to pretty much do what you want.
3. How common is reinforcement? Often you hear that the IG Regiments are never reinforced and fight to destruction. However if Vostroya frequently reinforces it's regiments from the homeworld how common (or possible) is this practice?
Again, this can be as flexible as you need it to be. If you want your Regiment to be reinforced with replacements from the same world part-way through a campaign? Fine. You want them to take on replacements from other worlds? Go for it. You want them to be merged with another under-strength unit? Great. You can make it fit for your own needs.
And one regarding naming conventions:
4. Obviously, the Imperium is an Empire, lead by an Emperor - so it would naturally follow that the Guard is an 'Imperial Guard'. However, there have been Regiments with 'Royal' in their title. By extension this would denote that a 'Royal' (Not Imperial) Dynasty is in existence. If so, is this an indication that the Imperium does contain smaller 'Kingdoms' (Maybe a few planetary systems united under one governor ala Ultramar) who are left alone as long as they obey the wider Imperium?
Once more, you free to pretty much do what you want. The
IoM is so monumentally vast, with such a diverse number of worlds and
IG regiments, all with their own cultures, tactics, naming conventions, rank structure, languages, etc... the possibilities are endless. Abnett has the Royal Volpone in his Gaunt's Ghosts series - a Guard Regiment from such an affluent, privatised world/culture they all have carapace armour and hellguns! So, go wild.
