I can only name some: Expellyermus , Lumus and Expectropatrono
Incendio!
You could try the Summoning Charm (Accio) to summon it.
The spell Expelliarmious saved Harry in the graveyard. Harry says so in book #5 The Order of the Phoenix, chapter 18, page 392.
In Harry Potter, the spell "Reducto" essentially breaks it. For example, in Order of the Phoenix, Parvati Patil reduces a table to ashes, while Harry uses it in GOF to break apart the hedges in the maze. It basically damages it, depending on the object you use it on.
Speaking on the red carpert (to Edith Bowman) for the 7th installment of Harry Potter, Paije Richardson confirmed that he was indeed in Harry Potter (from the fifth film onwards). He is one of the extras in the background. You can see him in Dumbledore's Army when Hermione casts a spell on Ron.
Excepto Patronum!
Digitalis is not a spell in Harry Potter.
In the book Harry Potter and the Order of the Phoenix, Molly Weasley casts an Imperturbable Charm on the kitchen door at Number 12, Grimmauld Place in order to keep eavesdroppers (namely Harry, Ron, Hermione, Ginny, Fred and George) from overhearing the meetings of the Order (of the Phoenix).
It should be Harry Potter & The Order Of The Phoenix as that is when they founded Dumbledore's Army and when they actually did Patronuses.

Fox is a correctly spelled word, but most likely you are looking to spell the word Fawkes, which is the name of Albus Dumbledore's pet phoenix.
Harry Potter's favorite spell was Expelliarmus (disarming spell) but he also used Stupefy (stunning spell) a lot.
