Gerardo,
Relative to using the De-Esser Plugin, I think once you locate the frequency of the sounds that are a problem, you would narrow in on that frequency in the selected audio and apply the De-Esser Plugin. A description of the De-Clicker and De-Esser Plugins are here along with links to the Plug-Ins:

I think that unless you are really good with Spectograms, the adjustments you need to make are going to be trial and error. When you look at the first noise, it stands out nicely. The other two are likely mixed in with audio that you want and so pulling off the noise in those cases likely will not work well. You probably want to look at the 4 part Spectral Editing Mini Course by Paul Licameli – the person who worked on the Spectogram feature for Audacity. The links to those four parts are below:

I’ll tinker with your audio when I get a moment and see if there is anything I can come up with.
