Have checked the lua documentation and haven't found the function that ouput specific value from the memory address. Is there a function in lua that allows to output the memory address value?

While this doesn't work with nil, boolean or number types, you can use string.format:

("%p"):format(my_object)

to get a string representation of the memory address of the object behind the variable my_object in vanilla Lua.

Or if it is not a string you do 

blabla = tostring(obj)

If you are working with LuaJIT, you can create this function yourself (works only on x86-32): 

read_memory_dword = require"ffi".cast("__fastcall uint32_t (*)(uint32_t)",
                                      "\x8B\x01\xC3") -- mov EAX,[ECX] / ret
YourValue = read_memory_dword(YourAddress)
