Turin went from underneath glaurong and when glaurong was asleep. I dont think Feanor could beat glaurong unless he was in the same situation has Turin. Face to face like at the bridge when glaurong first met Turin i dont think Feanor would have much chance. It would take feanor fingolfin and Turin to beat glaurong. Or maybe just Feanor and Fingolfin if they stood apart so glaurong could freeze them both. you know what i mean with the eyes. he has to look at them.

Túrin was a mortal man, and his spirit wasn't as great as Fëanor's (far from it). We don't know how much Glaurung's spell would have affected (though I do think it would have affected him, but not as much).

Feanor cant kill glaurung alone. Face to face Glaurung would kill feanor (and feanor is my fav of the noldo) but glaurung was too evil. Feanor would need to make a brilliant sword and armour for himself if he would stand any chance of killing glaurung.
With Turin and Fingolfin on Feanors side i do believe they would win. But it wouldn't be easy even then.

C,mon no way. Dragons are the worst most strongest things even in middle-earth. Im tellin you now you cant fight a dragon like that.

Well he was stated to be the most powerful maia who allied with Morgoth. He was also mightier than Saruman aka Curumo who was was stated to be "mighty among Aule's people (or something to that effect)". I can't be sure, but it may have been hinted at that Sauron was the most powerful maia of all, but I can't back that up.

I don't know if it ever says who the most powerful was.

It does state that Eonwe (Manwe's herald) was "The mightiest in arms in Arda" (arms as in weapons)
And that Olorin was the wisest.
