What colour is the short link wire?
Are there any earth wires (usually a green and yellow or green sleeve would be over the end of them)?
Is there any tape round the end of any of the cables to mark them as switch cables?
I'm not a qualified spark, but I assume that one of the lights (probably landing) will have a second switch upstairs. If that is the case then I think the 2 reds will be live supplies coming in from the lights, the blacks will be the switched lives and the grey will be a second switched live to operate the 2 switch light. I'm guessing again but the link wire sounds like it should be an earth connector.
Depending on the setup in your house The 2 red cables may well be from different circuits on your fuse board; one for upstairs lights and one for downstairs.
