Why are most of KBOS's instrument departures and arrivals jet-only?
Performance.
And the fact that most of their traffic is jets.
The difference is, "jets" are pretty much all capable of accelerating quickly to 250 knots and climbing out expeditiously, and ...

How to guess the actual name of the SID, waypoint, etc., if you have never seen it when told by ATC?
You can't, there is no system to them (at least no globally consistent system, airports may have a system for their own STARs and SIDs, and some countries for numbering airways, but nothing worldwide)....

Does a "climb and maintain" instruction override a "climb via the SID" one?
If the controller issues a "climb via" SID with an interim altitude of 8,000 and then subsequently amends the altitude and states:
"Climb via SID and maintain Flight Level 240" then the altitude ...

Anybody know the reason for the ‘Star Wars’ themed STARs into KATL?
It's a long established practice for the procedure developers to build the procedures around a theme. It helps with coming up with the necessary distinct pronounceable names for the waypoints.

Can I fly a STAR (standard terminal arrival route) if I can't maintain the minimum speed for it?
If you’re flying low and slow, in practice you’re not going to spend much time on a SID or STAR unless you lose comms. ATC would rather vector one plane (you) off the procedure so the dozen jets and ...

Is my procedure correct for simulated flight approach using this IAP after complete STAR?
First of all, what you show is not a STAR. There are several STARs at LSZH that end at AMIKI (NEGRA 2A, RILAX 2A, TRA 2A). What happens after AMIKI is the approach transition.
There are 3 ways to get ...

What's the precise meaning of "landing south (north, east, west)" in STARs?
"Landing south" means the planes are facing south as they land. Depending on conditions, they could come from the opposite end of the runway, and would be "landing north." This is also referred to as "...

Can SID/STAR have shortened names?
According to the Jeppeson chart legend[pdf] those are database identifiers. I'm presuming that's what would show on a menu in the FMS.
