What is a developing star not yet hot enough to engage in nuclear fusion called?
A protostar. See related question.
When does a newly forming star have the greatest luminosity?
A rotating nebula (a cloud of gas and dust) collapses under gravity. This creates a lot of heat energy. A "protostar" forms, before nuclear fusion begins. When the core temperature is high enough, hydrogen nuclei can undergo fusion and become helium, releasing nuclear energy. So, eventually the protostar becomes a "true" star and reaches the Main Sequence on the HR diagram. The newly forming star has its greatest luminosity during the earlyprotostar stage. (The protostar has a much bigger surface area than the final star.)
What does proto mean in protostar?
Wiktionary: "Prototypical; preceding the proper beginning of something". That sounds about right, for a protostar.
Is a protostar a collapsing nebula?
This is a very good question. And the short answer would be YES. Actually much more has to occur before nuclear fusion takes place in order to create a full star, but yes this is the beginning of the process. Remember "KEEP LOOKING UP." :)

How long does a protostar live?
A protostar will live as long as 100,000 years. After material stops falling on the protostar it will enter then T Tauri star phase.
Protostar will turn into what kind of star?
That depends on the mass of the proto-star.
Who named the protostar and why?
No one. It comes from the Greek - proto - meaning first. So first star - a protostar.
