if first monster name address in my game is

Code:
r=readInteger("[game.exe]+220")

the 2nd is
0x220+1c68 =1E88

Code:
r2=readInteger("[game.exe]+1E88")
+1c68 . ... . . .

r3=....

Is that possible to make auto increment to get all monsters addresses ?

Sure, though you do need some way to tell how many monsters there are so that you know when to stop.

1 way is to assume you know (or can find) a length:

Code:
-- get numeric address
local enemyBase = getAddress("[game.exe]+220")
-- loop over each enemy
for i=0,length-1 do
  r=readInteger(enemyBase+0x1c68*i)
  -- do something with r, eg. table.insert(enemyList, r) or writeInteger(enemyBase+0x1c68*i, r-100)
end


you could also assume that there's a 0 value after the last enemy (like how C strings are 0 terminated) eg,

Code:
local i=0
while true do
  local strAddress = "[game.exe]+" .. string.format('%X', 0x220 +0x1C68*i)
  r=readInteger(strAddress)
  i=i+1
  if r == 0 then break end -- stop the loop if done
  -- do something with r
end
