Not sure where to begin...
Well, first, if you want to take something valuable from the this, first of all focus on what you did, not what the others did. You never will have control over the actions of others, but you can change what you do.
So about the actual dive:
1. The type of dive you are describing is one time controlled by a limiting factor... could be air, could be the no deco limits, but each member of the team needs to know which it is and when it is reached. Yourr deeper diver obviously becomes the no deco limit controller, and is most likely the to also be the gas limiting one (but not a given).
2. For the team to know when gas is limited, they each need to know who is going to run low first...and if that is the limiting factor, then that diver is controlling the dive. The best way I know how to do this is to know your buddies breathing rates, and then watch them during the dive for how they are breathing. In this case, you are not going to know that, so it means doing a couple of gauge checks during the dive (I usually do 2...well 3 if you count on the surface - one about 5 minutes in... and one just over what you expect to be around half the dive). Once you have the limiting diver, all you need to pay attention to is where their gas is and how you relate to it.
Note: you get to learn to do this really fast when you take a class out with several assistants, as you have to manage a group of divers and not just one or two.
As you are now focused on the faster air user, you also need to focus on the deeper diver.. which is easy, because it is the same person.
If, by the way, you were all at the same depth, and you have different computers, you need to ckeck each of them (unless you happen to know how liberal or conservative they are).
On the safety stop...iT'S A SAFETY STOP first and foremost. It should be the one time you have a small break to get you gear together, make your plan and relax.
And if putting your long hose back contributes to your task loading, you might want to either practice with it till you can do it in your sleep, or not use a long hose... sorry.
In general, I am not a fan of doing night dives with divers you have not dove with before and know their skill level. But if I do, I am even more concerned about their management skills than I would be during a daylight dive. Some people have difficulty reading gauges at night... some people breath a lot more at night.
