First, of all those things you listed, only the water pump and lights are really on the 12v circuit (fridge draws a little from it).
The answer to your question is probably "yes, it's normal", but it really depends on how much they dimmed. The water pump draws quite a bit of current (for the short time it is on). That's always going to cause some drop in the voltage, which you'll see as dimmed lights.
