Technically, he didn't say it. He tweeted it. I realize that's Clintonesque parsing of the English language, but it works for both of them. Also, he claims he was joking. And, IIRC, Hillary claimed that Trump believes it is a hoax. Trump did not say that he believed it was. Also, perhaps a bit of hyper-technical parsing, but actually defensible.
That's hardly a lie. It was a misstatement. Is he lying also if he mispronounces somebody's name? His point, which virtually everybody understood, was that Hillary has been in positions of governmental power for decades, so her claim that she has some new ideas or wants to change things is disingenuous. Otherwise, she would have already implemented those changes.
It's not a particularly meaningful claim, but no doubt he had an opinion on the Iraq War shortly before it began, while it was going on, and also after the initial phase was over. What he said on Howard Stern many months before was not necessarily is final opinion on the subject. People change their minds, and there was certainly plenty of time to do it.
Once again, it's probably a silly, unproven claim, but it's equally difficult to prove that he's lying. Just because he may have voiced support at one particular point in time, it doesn't mean that he didn't change his mind later (whether before or after the intervention started).
The number of murders in New York City for 2015 was higher than for 2014. Nationally, the number of murders was much higher in 2015 than 2014.
Probably a lie, although I can see if his statement was stripped out of context, he might have thought it was reasonable to claim he never said it since context could reasonably be seen to be part of the statement.
If Ford has the choice between building a new plant in Mexico and in the US, and it chooses Mexico, then that's clearly moving jobs to Mexico from the US. Perhaps not existing jobs, but potential future jobs, which I think makes the statement sufficiently true. I bet that existing jobs get moved too, since although there probably won't be layoffs, there will probably be downsizing in the US through attrition. That is, people who resign or retire will probably be less likely to be replaced. And the jobs (not necessarily Ford's employees) existing to support that infrastructure will also disappear over time.
And a pretty big failure. Obviously, you can't really tell the difference between a lie and conventional political rhetoric.
