Jerry,

It is not clear in which Logo you are working.
Or do you want to know which are the possibilities of any Logo?

I can tell you how it is in Comenius Logo (SuperLogo):

When you create more turtles, then the oldest one will be at the bottom -
older turtles go behind younger ones.
If you want to bring one turtle to front, you just re-create a turtle with
the same name without any additional settings and that turtle will become
the yougest one without changing its other settings.
You can even re-arrange the order of turtles using a REORDER command.
REORDER [T1 T2 John] means that from now T1 will be the oldest turtle, T2
is 'one level' youger and John is the youngest one (from these three). If
there exist any other turltes then they will be youger than John keeping
their relative ages among each other as before the REORDER command.
