Well, i'll try to explain a bit.
First, what the connection types are used for.

When creating a building model, you'll need to tell the simulator about 
the state of the environment on both sides of a wall. The inside of the 
wall is in a room. You don't need to tell the simulator anything about 
it because that's what a simulator should calculate...
But you need to tell it about the outside of walls.
This is of course necessary so it can compute heat flux, radiation 
exchange through the wall etc.
For walls where both sides are inside the building the simulator can 
figure it out on its own, but for walls facing the outside you have to 
tell it about the outside using the connection options.

People, please correct me if i'm wrong here:
> exterior
Choosing this option makes your wall an exterior wall. Conditions are 
taken from the climate file (temperature, sun etc.)
Usage of this should be obvious.

> dynamic (similar) boundary
This sets the outside of the wall to be the same as the inside. (Like 
the wall wouldn't exist at all)
You can use this when simulating only one in a row of rooms where each 
room has similar conditions.

> static boundary conditions
Asks you for a fixed temperature etc., which stays constant over the 
simulation period.

This is for floors and cellars. It lets you embed your wall into the ground.
The profiles are temperature profiles defining ground temperature for 
each month. There are a variety of standard profiles pre-defined and you 
can make your own. (Climate files don't have ground temperature data, 
therefore you'll need to supply it in these options)
The 3d thingy is unknown to me.

This already says everything...

I don't know these.
Browsing through the mailing list archives i found this link describing
