Yes, Kosher meat is halal for Muslims to eat
If Muslims do not have access to halal meat then kosher meat is acceptable.
Not much difference - Halal is practiced by Muslims, and Kosher is practiced by Jews. Neither eat pork, and each have requirements on how their meat is slaughtered and processed.
A Jew who keeps strict kosher cannot eat halal food since the standards in kashrut are stricter than in halal. In kashrut, (1) mixing meat and dairy is prohibited, (2) more animals are forbidden relative to halal, (3) halal slaughter techniques are less strict than Jewish ones.
Yes it is. Now there is a distinction between what is Halal (permitted) and what is Thabeeha (Islamic slaughtering of meat which has certain specific requirements that may not be done in Kosher slaughtering). But permitted would be anything that is truly Kosher.
It is halal if from halal meat.

No
Completely - no. In part - yes; and for various reasons. Some Christians try to observe the literal laws of the Torah. Some Muslims buy kosher meat when they have no source of Halal meat (meat prepared in Islamic tradition). And some Westerners, particularly in America but kosher meat (or other products) because of the generally high standards of cleanliness and/or healthiness in kosher food.
