Does it mean that every form of life on Earth (right now) evolved from the "Parent" of the Comb Jelly ?

No, just animals. Not prokaryotes, archaea, amoebozoa, etc.

Not the parent, but some great-grandparent, yes.

See https://en.wikipedia.org/wiki/Last_universal_common_ancestor for more info:

> The LUCA is not the first life on Earth; it may have lived among a diversity of other organisms whose descendants all died out. Rather LUCA is the most recent form from which all surviving life on Earth is descended.

No, there are many forks before that one.

If this stuff interests you I would like to recommend Dawkins' 'The Ancestor's Tale', it is pretty accessible and walks you back through time step-by-step.
