This depends on the complexity of the experiment and the specific research question being asked. In general, it is recommended to only change one variable at a time in a controlled experiment in order to accurately determine its effects. However, in more complex experiments or for certain research questions, it may be necessary or valid to change multiple variables. So, it could be anywhere from 1 to 4.
