If a motherboard has only 4 RAM sockets, then can we add more up to 5 or 6 sockets?

No. The memory control logic is a fundamental feature of the motherboard, not something extensible.
If You use Linux and have GPU with lot off RAM: http://kerneltrap.org/node/143
You can also use i-RAM storage device and make swap on it: http://techreport.com/articles.x/9312/2.
I think both options are to expensive and complicated for normal use, but it's possible.
One more interesting link (it can by consider as a little off topic but in my opinion somehow related): http://en.wikipedia.org/wiki/Remote_Direct_Memory_Access
