ᐅ Multi-Service Building Entry – Telecom and a Fourth Utility Line?

HausnerHello,
we are getting a multi-utility house entry from Hauff. The first two utilities are the house connections for electricity and water, which will be routed there, as far as I understand.
The third utility is telecommunications. If I understand correctly, a large empty conduit (e.g., Kabuflex DN75) is connected to this utility outside the basement and runs to the property boundary. Here are a few questions about the telecom utility (marked A):
A1. Question: The telecom company then pulls their telecom cable through this empty conduit, guides it to the property boundary, and connects it to the existing telecom cable there (in my case the cable comes about one meter out of the ground, with an outer diameter of just under 11 mm). Is this correct?
A2. Question: Parallel to this (i.e., inside the 75 mm Kabuflex conduit), another empty conduit (Speed-Pipe for fiber optic cable, outer diameter 12 mm) is installed, right?
A3. Question: According to my understanding from Hauff customer support, the telecom utility can accommodate 5 cables (1 x 13-21 mm, 3 x 7-13 mm, and 1 x 5-13 mm). That means I would have 3 free connections for the future and could push further cables through the Kabuflex empty conduit if new technology or similar developments arise. However, the Kabuflex conduit is about 50 m (165 feet) long (we are building on a back lot) with 3 90-degree bends. Is it realistic to expect to be able to pull additional cables through the Kabuflex conduit later on?
A4. Question: As mentioned before, we are building on a back lot. We even have a second driveway and *two* possible locations from where the fiber optic cable could be routed. A Speed-Pipe conduit was also planned at the second driveway. How do I get the Speed-Pipe conduit from driveway 2 into the Kabuflex conduit that leads to driveway 1? For example, is it advisable to slightly slit open the Kabuflex conduit near the multi-utility entry point and insert the second Speed-Pipe there?
I also have further questions about the fourth utility (marked B). This is normally gas. We do not have gas, and I would like to use this utility to lay cables to my garage.
B5. Question: Can I select a similar utility insert for this utility as for the telecom utility so that I can also route 5 cables through it (1 x 13-21 mm, 3 x 7-13 mm, and 1 x 5-13 mm)? I would then run 5 x 10 mm² underground power cables (outer diameter 20.4 mm), underground LAN cable (outer diameter 8 mm), telecom underground cable for sensors (10 x 2 x 0.8, outer diameter 12.5 mm), and KNX underground cable (2 x 2 x 0.8, outer diameter 9 mm) to the garage. This should just about fit, and I would even have one connection free for the future (the route to the garage is quite straight and only a few meters), or am I overlooking something here?
B6. Question: The empty conduit to the garage would exit the ground next to the garage. Later, I would drill a hole near ground level in the garage and insert the cables there. How do you seal the empty conduit and the drilled hole on the garage side?
And one general question:
C7. Question: How exactly is a Kabuflex empty conduit connected to the multi-utility unit?
Thanks a lot in advance for your answers.

Is it realistic to expect that I will ever be able to pull anything else through the Kabuflex conduit? I would recommend changing the 90-degree bends to 45-degree bends instead; otherwise, I see you having to install the entire run all at once within the same construction phase.
