Is usage of "kindly" above right?
Typically, on and upon are both prepositions that can indicate time and place.
depend on and depend upon essentially mean the same. However, I would say that at least in AE (American English) upon is considered a bit more formal, and would be used for emphasis.

She depends on her parents for support.

Both of these mean the same thing.

I'm really depending upon you to be there for me.
Again, both of these mean the same thing.
