So when this power is used, it makes it so that your republic unique jedi's can share their force powers once per turn. Does this mean then that every unique jedi in your squad can use each one of each others powers all at once? For example, can Obi Wan Kenobi, Jedi Padawan gain Master of the Force 2 from Joruus and Dark Tempataion from Ferus Olin and use both on the same turn to do a Use the Force on a double attack while using Dark Tempation and possibly having Overwhelming Force?

I'm a little confused by this power at the moment, but I love the power, cause it makes for some interesting squad builds. I think it would be really cool to be able to make Obi Wan Kenobi, Jedi Padawan as powerfull as I stated in my example.

No. You only get to borrow one Force Power per turn. If Obi uses Force Renewal 2 at the beginning of his turn, he can't borrow any other powers that turn. He could choose to borrow Lightsaber Riposte on an opponent's turn, though.

Is Master of the force 2 also a force power that a character may borrow?

Therefore allowing a character to use more than one of IT'S own force powers.
For instance-
Feris using Dark Temptation and Lighsaber precision?
or a Jedi Weapon Master reposting two seperate attacks in one turn?

yup

And if I have Qui-Gon Jinn, Force Spirit can all of my force users use Sense the Future?

Well, technically, ANY of them can, but it's a once per round Force Power so I guess it would just be a matter of choosing whoever had the most Force Points.

no,

MMM allows you to share force powers ONCE PER TURN.

When abilities like Sense the Future, anticipation and surprise move are being used there is no turn happening and therefore does not qualify for MMM to be used.

Similarly, if someone intuitions or attacks during the initiative phase there is no turn happening so MMM is unable to influence any Jedi that might be able to react (like boosting an AoO with Dark Temptation or the like)
