I think many of those can be closed as not a real question. You could leave a comment to ask for more information when the asker is still active.
When I say "many of those", I'm making a wild (though educated) guess as to the ratio of good/bad questions that follow this pattern. My guess is that many of the questions which can possibly fit entirely in the title of a question would qualify as "not a real question" because they won't be detailed enough to be answerable.
That is, that it qualifies that "it's hard to tell what is being asked here", to paraphrase the close reason.
I should have been more careful, though, to state that it is not merely the fact that the question fits entirely in the subject which causes this. It is certainly possible to craft an appropriate question in such a short length. It's just hard to do.
In some of the cases, you could leave a comment to request that the asker flesh out their question with more details. You might do so with or without also issuing a vote to close as I noted above. I don't think the judgment there is any different than any normal question which might apply as "not a real question".
Another item I realize I could have been more detailed about: If I was not at 3K reputation on the site, I would probably not flag most of these questions as not a real question, as that is demanding that a moderator make an up-or-down decision on the spot. I would instead leave a comment (if the user is still active), and only flag it if it's really, very clear that it is "not a real question" in any way, shape or form.
Being a 3K user on Stack Overflow, though, I would vote to close as NARQ. In fact, I did so on each of the three you posted. I feel the 'vote to close' option is a bit less strong, because it requires 5 votes to close, so others must agree with me.
I think I see that you flagged a number of these questions as NARQ, and perhaps you did so in response to my initial answer. If that's the case, I deserve the down votes I got on this! I deserve them anyway for leaving this answer so simple for so long... bad me! (FYI: I truly don't mind DV's like these, anyway.)
