I use them quite often but I'm not sure what to call them. Their pictures appear in these links.

Should I call what is depicted in the first link a water spray bottle or a water sprayer? The picture in the second link is a black thingI put CDs through. Can I call it a pole or spindle?
bytebuster has the provided the correct term, although I would parenthesize it like this: (hot air) balloon. That is, these objects can simply be called balloons, or hot-air balloons if you want to be more specific.
Also, it may be worth noting that many dictionaries hyphenate the descriptive hot-air, although that hyphen is regularly omitted in the literature.
Hot air balloons belong to the family of flying machines called aerostats, or lighter-than-air flying aircraft. However, it should be noted that I've added that hypernym simply for reference purposes; the word aerostat is a more technical term that's seldom heard in day-to-day speech. In conversation, I'd expect to hear something more like:
Blimps and hot-air balloons are lighter-than-air aircraft.
What are those called? Bon-bons or something like that?
I think you might be mixing up pompons and bonbons.
A bonbon is a piece of candy, often covered in chocolate.
A pompon is an ornamental woolen ball.
The word pompon in English can also be spelled pompom or pom-pom.
For what it's worth, I found these images on Google by search for pompons and bonbons:

As implied by that second definition, if OP specifically wants to refer to the "pole" in the middle, it's always called the spindle.
