Is it true that there more lods you create - the bigger the map/ ram load would be?
Does RAM load depend on size(in MB/GB) of the map, or does it unload the object the player doesnt see?
Add LODs to an object hardly makes any difference to the asset size.
You can tell how big an asset is by right clicking on it in the browser and choosing ‘size map’.
Then try giving it 5 LODs. It makes about 1% difference.
Yes, it all needs to be in memory at runtime.
Oh thats not good 
A model a freelancer made for me is occupying 300mbs of memory, as per Map Size. It is 1 million polygons(a little bit of an overkill, lol) and has a lot of material slots. I added 7 LODs, in order for it to be under 100K tris. But it did make an impact though, the model is now occupying 500mbs of memory.
Hopefully the final build will only cook the minimum lod and higher
