You don't need an extra script for this. In "Last instance only" mode all previous script instances are stopped once new value arrives.

Your script should be modified to turn off all outputs when false is received. This is needed because when the script is running it's mostly sleeping with one output turned on.

Code:

value = event.getvalue()

function dosleep(obj)
  local timer = grp.getvalue(obj)
  timer = tonumber(timer)

  if timer then
    if timer < mintimer then
      timer = mintimer
    elseif timer > maxtimer then
      timer = maxtimer
    end

    os.sleep(timer * 60) -- minutes -> seconds
  end
end

mintimer = 0.1 -- minimum timer value in minutes
maxtimer = 60 -- maximum timer value in minutes

objects = {
  {
    output = '5/1/1',
    timer = '5/3/1',
    enable = '5/4/1',
  },
  {
    output = '5/1/2',
    timer = '5/3/2',
    enable = '5/4/2',
  },
  {
    output = '5/1/3',
    timer = '5/3/3',
    enable = '5/4/3',
  },
  {
    output = '5/1/4',
    timer = '5/3/4',
    enable = '5/4/4',
  },
  {
    output = '5/1/5',
    timer = '5/3/5',
    enable = '5/4/5',
  },
  {
    output = '5/1/6',
    timer = '5/3/6',
    enable = '5/4/6',
  },
  {
    output = '5/1/7',
    timer = '5/3/7',
    enable = '5/4/7',
  },
  {
    output = '5/1/8',
    timer = '5/3/8',
    enable = '5/4/8',
  },
  {
    output = '5/1/9',
    timer = '5/3/9',
    enable = '5/4/9',
  },
  {
    output = '5/1/10',
    timer = '5/3/10',
    enable = '5/4/10',
  }
}

for _, item in ipairs(objects) do
  if value == true then
    if grp.getvalue(item.enable) then
      grp.write(item.output, true)
      dosleep(item.timer)
      grp.write(item.output, false)
    end
  else
    grp.checkwrite(item.output, false)
  end
end
