Does all yogurt have live probiotic acidophilus in it? Or just the yogurt that is labeled that it has live?!

The term "acidophilus" is sometimes used to describe any bacteria that aids in human digestion, so if that's what you mean, then all yogurt has live acidophilus (assuming it's fresh as opposed to "frozen yogurt", which often isn't really yogurt at all, and also assuming it's not so old that all the bacteria have died).

But if you are referring specifically to Lactobacilus acidophilus, then no; a few yogurts are made only with other bacteria. These are usually labeled as such, for people who can't eat acidophilus for whatever reason.

No.

First, some things labeled "yogurt" may no longer have live cultures in them, though they had to have been fermented with them in the first place. In other words, to increase shelf life, etc., some are heated so high later in production that the "good" bacteria are killed and the product then becomes basically pudding.
The yogurts that still contain live cultures will say something like "Contains Live Cultures" (not "Made With" Live Cultures) somewhere on the carton, or have the stamp of the association that verifies those things on the carton.

Also, to be sold as "yogurt" in the U.S., the two specific strains that have to have been used are lactobacillus bulgaricus and streptococcus thermophilus (lactobacillus acidophilus is actually optional). U.S. "yogurts" may contain other strains if they want, but must have those two.

You can get loads more info about all that in my two answers to these previous questions if you're interested:

I'm not sure, but I think all yogurt has that. Actually, probiotics are excellent and healthy for you, so you shouldn't get too worried about it.
