Until yesterday I did not even know that the noun proudness exists. I always thought pride was the only possible noun for the adjective proud. Is there actually a difference between the two nouns (pride and proudness) or can they be used interchangeably in every case?

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information. See the FAQ for guidance on how to improve it.
Here's what the OED says:
proudness Now rare. [f. proud a. + -ness. ] The quality of being proud; pride.
As can be seen, the most recent cited use (not mention) of proudness by an adult was in 1606 and was spelled Prowdnes. The OED says it's "now rare".
But what you say or write is up to you, as always.
