If we assume that "north" on the moon aligns with the Earth's north, then as the moon orbits the Earth, the sunrises on the moon occur in the east. This is because the moon rotates counterclockwise once a lunar month, as it makes its counterclockwise orbit about the Earth. The Earth itself rotates counterclockwise also, so both the moon and Earth would share eastern sunrises.

If you just look at the moon during the first quarter moon, it's easy to see that the line of twilight moves westward on the surface of the moon, so that the sun will appear to rise in the east.

I think it will still rise from the East. The rest of the text explains my reasoning.
Hm......Let's see the facts:

1) If we position ourselves above Earth's North pole, the moon revolves in anti-clockwise direction around the Earth. (we don't need to care about Earth's orbit direction around Sun in this case but it's anti-clockwise too anyway. http://library.thinkquest.org/29033/begin/earthsunmoon.htm can verify this.)

2) Every time when the moon is visible on Earth, we see the same part of it. This show that 1 moon's rotation on its axis takes 28 days (which is also the time take for one revolution of moon around the Earth) to have this effect.
(use an apple and a ball if you don't understand this. Revolve the ball around the apple ensuring the same surface of the ball faces the apple and you will see the ball will complete one rotation with one revolution.)

3) Sun rises from east on Earth.

All these informations are sufficient to construct a model of the Sun, Earth and the moon in relation to each other.
Try it out with 3 coins of different sizes or 2 balls and a light source.

Assume the top part to be North pole. Rotate the 'Moon' ensuring the same surface faces the 'Earth' as it revolves around. Take note of how the light from the 'Sun' will appear and disappear from a certain point on the surface of the 'Moon'. Assuming that North of the Moon is corresponding to the Earth's north, the light on Moon should appear from the East, meaning Sun will rise from the East.

Very Interesting question to ask.

The Sun, the Moon, the planets, and the stars all rise in the east and set in the west. And that's because Earth spins -- toward the east.

For a moment, let us ignore Earth's orbit around the Sun (as well as the Sun's and solar system's revolution around the center of the Galaxy, and even the Galaxy's journey through the Universe). For the moment, let us just think about one motion - - Earth's spin (or rotation) on its axis.

Earth rotates or spins toward the east, and that's why the Sun, Moon, planets, and stars all rise in the east and make their way westward across the sky. Suppose you are facing east - the planet carries you eastward as it turns, so whatever lies beyond that eastern horizon eventually comes up over the horizon and you see it!

People at Earth's equator are moving at a speed of about 1,600 kilometers an hour -- about a thousand miles an hour -- thanks to Earth's rotation. That speed decreases as you go in either direction toward Earth's poles. In the state of Texas, you'd moving at about 1,400 kilometers an hour due to rotation. If you're in southern Canada, you're moving at only about a thousand kilometers an hour. Now think about what would happen if you stood exactly at the North Pole. You'd still be moving, but you'd be turning in a circle as Earth spins on its axis.

You may wonder why you don't feel this speed: it's because human beings have no 'speed organs' which can sense absolute speed. You can only tell how fast you are going relative to something else, and you can sense changes in velocity as you either speed up or slow down. But we cannot really tell whether or not we are just moving at a constant speed unless something else tips us off!

Think about this:
Suppose you are in a car traveling down the road. How can you tell how fast you are going? The speedometer tells you how fast your wheels are turning, but you could be standing dead still, spinning your wheels trying to get off a patch of ice, so let's remove the speedometer from the car. As you go faster, your car may vibrate more because it's working hard, but these vibrations only tell you the car is working hard, not what velocity you are moving at. So get a good car and some cushions to remove the vibrations you feel. Then get some good earplugs so any misleading sounds won't distract you. And paint your car windows black so that the motion of objects relative to you don't throw you off. Remember that when it comes to the rotation of the Earth, everything around you is moving at the same speed - you, the trees, the houses, your pet dog, everything. OK, now, how fast are you going? You have no way to tell. You don't feel like you're moving. You feel just as you would if you were standing still! Human beings have no ability to tell absolute motion.

All planets & their natural satellites in solar system are spinning in counter-clockwise direction. So Sun always rises in the east as per their their view.

But their's one exception :
Venus is the only planet which spins westwards.
So Sun rises in the east on Venus.Right!

it depends which side of the moon you are standing if you standing on the hidden side of the moon its rise from the east

I'd say yes.
