Answer 1

You are using a non LTS version of Nodejs. See the Node Version Support section of the docs for details of the support matrix. This just means its not well tested or supported on the non LTS versions hence the warning. You can ignore the warning if you are just developing/prototyping but for production you want to use one of these LTS versions.

Answer 2

however, on page:

https://www.npmjs.com/package/@azure/msal-node
claims that:

Supported Node versions: 10, 12, 14, 16
Will support stable (even-numbered) Maintenance LTS, Active LTS, and Current versions of Node
