Do NEMA 5-20P plug fit in the 5-15R receptacle? I read 5-15R fit in 5-20P. However, I want to confirm if this works and Vice versa.

No. A receptacle's slot configuration determines which plugs it will reject as well as accept.

A 5-20 plug assures it will only fit a receptacle fed from a circuit capable of supplying it (20a).
 
will work only if you twist the blade on the plug :)

I took over maintenance of a radio translator a few years ago, installed at a two-way radio repeater site. Lots of receptacles mounted up in the grid above the equipment racks. The previous moron did just that with a 5-20P on a UPS. If he had moved over 2 feet to the next quad box, he could have plugged into a 5-20R. :(
