The super-ego functions are elements you're consciously aware of, but weakly. So, you feel as though you should be better at them. The reason why they are weak is because they oppose your ego functions. If your ego function is external then the super-ego is internal (e.g. Se vs Ne). Maybe a good analogy would be that the ego and super-ego both look at the same box (dynamic or static), but if you're inside the box you can't see the outside, and vice versa. They are socially normalizing. You tend to view them as societal expectations on yourself, so you may consciously ignore, fight, or attempt (but often fall short) to achieve things related to them. Areas of struggle and anxiety.
The super-Id is essentially a blind-spot in your cognition. Not only are you weakly aware of it, but it's also outside of your mental focus. Things related to the elements in the super-Id is what you expect of others. You subconsciously expect these things to be done and taken care of because you expect to not focus on them. The reason for this is that your ego functions often rely on these assumptions in order produce something. While the connection between complimentary elements isn't 100% clear to me, the best example I can think of is that part of the reason Se-egos are so instinctual and spontaneous is that they subconsciously make assumptions about consequences and chains of events (Ni-super-Id). Areas of expectation.
It's also important to note that Se-ego is synonymous with Ni-super-Id (and Ne-super-ego and Si-Id for that matter.) It's best to not view them as separate things but instead as just different names for the same thing. They are all connected and caused by each other. Weak unconscious Ni causes strong conscious Se. Weak conscious Fe causes strong conscious Te, etc.
The Id is our subconscious strength. It can be viewed as a byproduct of focusing on our ego-elements. In focusing on our ego elements we will often be dealing with these elements unconsciously. They are unnecessary to our ego, but since we are so involved with them they are viewed as an obvious irrelevance. There is no need to verbalize or make a big deal out of these things, and we relieve and disarm any focus on these elements which can be a relief for some and an irritation for others. Areas of disinterest and conscious disregard.
From another perspective (possibly a more Freudian one), the Id can be viewed as our most basic self, or our core self, and from it stems a mental focus on our ego elements. However, we still don't focus on this consciously and so the outcome is the same. The information related to it is innately known and consciously uninteresting.
