Apart from Abyss Break cast by Jellal, we've never seen any single mage cast a spell combining more than two kinds of magic. Even combining two kinds of magic into a single spell seems to be quite the accomplishment, so I don't think that Rufus not combining 3+ kinds of magic is downgrading him in any way.

But I think that he was able to find all those ancient, powerful and rare spells in that library was bullshit to begin with. This wasn't the royal library, the library of the magic council or any other restricted place... that was the normal town's library. Why are there books with very rare and powerful (and thus valuable) spells stored in there, without any restrictions? Any why did nobody else find those books before and learn their spells?

And Fairy Magic? Weren't those supposed to be super-secret spells known only to a handful within Fairy Tail?
