Q:

Diode datasheet reading

What is difference between single and common cathode configuration? If I want to use 2804 for rectifying, will it act as 2800?

A:

A 2804 is two 2800's, with their cathodes connected together, put in the same package. You could just use one of them, or you could use both in parallel.
