Do galaxies all spin in the same direction?

Which direction is the same direction? If you're looking at a spinning object from one side it may appear to be going clockwise, but if you look at it from the other side it appears to be going counter-clockwise. Which direction it spins depends on how you look at it. So this question is kind of impossible to answer.

To get at a more fundamental point to your question, there is nothing that causes galaxies to know how other galaxies are spinning and spin in the same way (whether it be direction, speed, etc.). Most galaxies are completely distinct from other galaxies and even those in the same group or cluster don't often interact much. For that reason most galaxies are just doing their own thing without concern for what other galaxies are doing.

No. Angular momentum is a conserved quantity, The net angular momentum of the universe should sum to zero. The spin of galaxies should be in random directions on average.

No - some spin in both directions at the same time!

It's all subjective. A clock will appear to move counter clockwise if you look at it from behind. But let's assume you have a frame of reference, they do not all spin in the same direction

No, of course not. Every galaxy has a unique speed and orientation. The space between galaxies is much too large for any galaxy to have much effect on any other galaxy.

No; in fact, some don't spin at all.

No. And clockwise vs counterclockwise really depends on what side of that galaxy you are looking from ("above" vs "below").

At all random directions. There is no correlation.

No
