Existing is using something like this.

Then my uncle bought this from outside.

Is it correct to connect the IN and OUT as shown above? Leave the other two holes empty right?
If your existing is the top photo, then the live goes in and out from it. The neutral from TNB will go straight to the RCCB.[attachmentid=10622252]

If you change to the 2 pole version in the bottom picture, you should not leave the second slot empty (The slot on the right in your picture, without your red lines)
Take the neutral from the RCCB and poke into the second slot. And then from this dual pole take 2 wires and go to the RCCB.
Argh, sorry, logically the RCCB should be on the left, so the busbar can feed the MCBs
Edit to add this image from the internet
