At least five.
The number of controls in an experiment can vary depending on the study design and objectives. Typically, experiments include at least one control group to compare against the experimental group, but researchers may include multiple controls to account for various factors, such as environmental conditions or specific variables. Ultimately, the number of controls should be sufficient to ensure the reliability and validity of the results without complicating the experiment unnecessarily.
as much data as possible can be colleced in the time availble
As many as you can find that would effect your experiment in some way.

What a stupid question. Because you should.

They shouldn't, ever. It defies the whole point of a controlled experiment.
As few as possible.

There is no set number, the number is dictated by the design of the experiment.
A experiment should only have one variable.
