Any hints on what I am doing wrong in example 3?
as in any prodedural language a function as argument gets immediately 
executed so you need to delay:


context.startplacefigure({title = "Figure"})
    context.startcombination({nx = "2", ny = "2"},
    context.delayed.externalfigure({"cow"},{width = "50mm"}), 
"Caption 1",
    context.delayed.externalfigure({"cow"},{width = "50mm"}), 
"Caption 2",
    context.delayed.externalfigure({"cow"},{width = "50mm"}), 
"Caption 3",
    context.delayed.externalfigure({"cow"},{width = "50mm"}), 
"Caption 4"

    )
    context.stopcombination()
context.stopplacefigure()

(this is why encoding complex documents completely in a scrtipt 
language is non trivial and why for instance these template systems 
are there because these accumulate)


Another solution is to use the content and caption blocks for each 
combination entry.


\starttext

\startluacode

context.startplacefigure({title = "Figure"})
    context.startcombination({nx = 1, ny = 1})
    context.startcontent()
    context.externalfigure({"cow"},{width = "50mm"})
    context.stopcontent()
    context.startcaption()
    context("Caption 1")
    context.stopcaption()
    context.stopcombination()
context.stopplacefigure()

\stopluacode

as in any prodedural language a function as argument gets immediately 
executed so you need to delay:


context.startplacefigure({title = "Figure"})
context.startcombination({nx = "2", ny = "2"},
context.delayed.externalfigure({"cow"},{width = "50mm"}), 
"Caption 1",
context.delayed.externalfigure({"cow"},{width = "50mm"}), 
"Caption 2",
context.delayed.externalfigure({"cow"},{width = "50mm"}), 
"Caption 3",
context.delayed.externalfigure({"cow"},{width = "50mm"}), 
"Caption 4"

)
context.stopcombination()
context.stopplacefigure()

(this is why encoding complex documents completely in a scrtipt language 
is non trivial and why for instance these template systems are there 
because these accumulate)

[NTG-context] combination with lua
