Maybe explore Power over Ethernet (POE) as an option. If the run is under 100 metres (328 feet) from the barn then you can get up to 15 watts per run of cable. All you need is a POE injector per ...

How to replace a 2-Gang 1-Way Light Switch with a 2-Gang 2-Way

It's not that critical. Both of these are "2-way"(US: 3-way) switches and yours is wired as 1-way. You can see where the switches are split left to right, they do a pretty good job on both ...
