yes. 21 will run on anything later than Android 5.0.
you should have a script that sets all the relevant environment 
variables as detailed in the readme and the helper scripts provided. If 
you change the SDK, change the env too to match (I think).
We are call currently building with sdk 21 and ndk 13b. All other 
combinations are YMMV.
We are also all (?) running 64 bit builds on NV shields or S912. Shields 
are faster and perform better. Wifi is also not so good so wired is better.

AFAIK, later sdks will not change look and feel much and any of the APIs 
that are exposed I dont think are needed. The java Qt harnesses would 
probably need to change a bit with a changed SDK. I have a 4.4.4 build 
that I tried with my TCL TV but memory (RAM) is an issue. At least 2GB 
RAM (more is pref) and faster is better (DDR4 vs DDR3) if you are 
getting a TV box. The GPU accesses main DRAM so this may limit the 
res/framerate that is achievable too.

That is correct. For release (something that can be submitted to the 
store) you need a key, and it probably needs to be registered. I have 
never done this step though.
