OK, I shall try to prepare the first post. It will take some time, though.

Did he? It is true he was the Lieutenant of Dol Guldur, but what about all the Nazgul flying around Pelennor and such? He definitely must have left Dol Guldur at least on some call before the Battle of Morannon. But wasn't he flying somewhere around above Pelennor even earlier?

Nowhere it is said that all the 9 or at least 8 (as the WK preferred his horse) were flying above the Pelennor. It is likely that Khamul was away on March 15, leading the assault on Lorien. Another proof is that being the Second to the WK, Khamul didn't take command after the Black Captain was slain, but Gothmog did (who I always thought to be another nazgul).

I have already counted the nazgul previously on the Entmoot ... let me see... here:

On March 15 3019, two nazgul (Khamul + another) must have been in Dol-Guldur, as exactly on the same day both Lorien and Thranduil were attacked. Perhaps, even three nazgul were dispatched North, as there were 3 goals: Lorien, Thranduil and Dale-Erebor.

So we have the WK and 5-6 remaining nazgul.

One was in Mordor - just before dawn he came to Cirith Ungol and REMAINED there in charge of the tower.

Another flew to Mordor from Pelennor while hobbits were running from Cirith Ungol:

They started off again. They had not gone far when Frodo paused. ‘There’s a Black Rider over us,’ he said. ‘I can feel it. We had better keep still for a while.’ Crouched under a great boulder they sat facing back westward and did not speak for some time. Then Frodo breathed a sigh of relief. ‘It’s passed,’ he said. They stood up, and then they both stared in wonder. Away to their left, southward, against a sky that was turning grey, the peaks and high ridges of the great range began to appear dark and black, visible shapes. Light was growing behind them. -The Land of Shadow

Perhaps, this one was dispatched by the Witch-King to Sauron to complain about the unexpected light.

Then comes the third nazgul - again from Pelennor to Mordor:

As Frodo and Sam stood and gazed, the rim of light spread all along the line of the Ephel Dúath, and then they saw a shape, moving at a great speed out of the West, at first only a black speck against the glimmering strip above the mountain-tops, but growing, until it plunged like a bolt into the dark canopy and passed high above them. As it went it sent out a long shrill cry, the voice of a Nazgûl; but this cry no longer held any terror for them: it was a cry of woe and dismay, ill tidings for the Dark Tower. The Lord of the Ring-wraiths had met his doom.-The Land of Shadow

This one brought the news of the Witch-King's demise.

So 5-3=2
If Gothmog was one of the two, then only one (or two) nazgul are unaccounted for.
- Maybe he was sent with the news of the coming of Aragorn? Or he simply remained in charge in Minas Morgul? Or maybe he stayed with Sauron?

As for the Black Gate battle, there were all the remaining 8 present, thus including Khamul.

Though it may seem funny, surely it ain't that easy, even for a Nazgul, to fly on the back of a Fell Beast.

And their training area was above the Dead Marches. It is much nicer to plummet down onto the slime of the Marches instead of the hard rocks of Gorgoroth.
