Answer 1

That is because in anaconda by default you will be in the base environment where the version of pyyaml is 3.13(in your case).
If you activate the environment yaml and check the version of pyyaml, you will find the 5.2 version of pyyaml
The problem in your case is that you are in the same base environment. Kindly use the following command to switch to the other environment.
conda activate yaml
You forgot to use the conda command before activate yaml hence you are in the same base environment.
Kindly follow this link also.
Hope this will help you.
