Footprint depends on the build: statically or dynamically linked
and on the number of features and/or appletts you compile in.

Don't know.

Don't know.

Don't know.

Don't know.

I think this is not related to busybox

I think this is not related to busybox. Use iptables?

Run: make menuconfig
and look under Networking utilities
> (7.2) Does BusyBox provide a Bluetooth stack ?
Would say no.
> (7.3) Does BusyBox provide a ZigBee stack ?
Would say no.
> (7.4) Does BusyBox provide a ZWave stack ?
Would say No.
> (7.5) Does Busybox provide a 6LOWPAN stack ?
Wouls say no.

Yes, If your system has the relevant c++ libraries.

Yes, if your system has the relevant java runtime environment.
> (9) Can applications be debugged while they are executed on the target ?
Yes, with strace and/or by enabling Busybox Settings -> Debugging options  at compile time. 
> (10) What is the long-term availability of BusyBox? Can it be expected to be available for at least 10 years ?
You download the source, you will have it forever.
> (11) Is remote login to a target possible, that is running with BusyBox? (e.g. with telnet or SSH) 
Telnet yes. SSH only if you install a separate SSH server (e.g. Dropbear)
