Currents split inversely proportionally to the resistance of the load when in parallel. When the loads are in series, the current is the same in each step of the series.

By superposition, yes, all the parallel currents add up.
As long as the voltage compliance of the source with the narrowest range is not exceeded.

EDIT: I actually did an experiment with a pair of JFETs. As long as the supply voltage was high enough to operate both devices in saturation, the resulting current was IDSS1 + IDSS2.

Make your own new rules with these two voltage (-2 to +2V) controlled current sources.
The reference current, voltage and load resistance. Which ones dominate the result in series?

Something is wrong with the bottom grounds.

The currents will add as if there were one source until the voltage compliance of one of the real current sources is reached.
Ideal current sources, such as in a simulator, have no such limit, of course.
