Questions about monsters with spontaneous spellcasting

[Conradine]

Nymphs can cast spells like level 7 druids.

May they teach the basics of Druid class to humans and elves?
It's possible that, in very ancient times, Nymphs taught to the very first human and / or elves druids?

Rakshasas and several celestials like Ghaeles can cast spells like clerics.
May they teach the basics of Cleric class to similarly aligned mortals?

How about Dragons and Wizards?

Dragons are Sorcerers, so that wouldn't work very well.

The other examples? Sure, that could work. But people can also self-discover classes. A Cleric could pretty much just be a dude who prayed until he got some cool divine magics.

Sure, no reason why not.

Ditto.. sure, yeah.

Err... Dragons and Sorcerers... but, yeah.

Or they could just be "taught by the gods," read a tome or scroll (that would then become 'holy text', etc.
