As for the camera and mic part,
If you simply search the web for phrases like "use Android camera/mic on PC", you will come across many apps; some of them actually do the job.
I have used an app called DroidCam in the past which had worked for me in Windows 7 after a litte bit of struggling. (I have never tried it in Windows 10, though; but I guess it should work)
As for the fingerprint reader part,
There is not a solution which can be assured to work flawlessly. But there are some things which might be helpful :-
Dynamic Lock by Microsoft — If you are simply looking for a solution to unlock your PC using your phone, then this might be the solution for you. Although it doesn't specifically use a fingerprint unlock, it allows you to keep your PC unlocked when your phone is close enough and reachable via Bluetooth.
Third-party solution — There is an app called Remote Fingerprint Unlock which is slightly complicated to set up but will do the job for you.
Samsung Flow — If you happen to have a Samsung Android phone, then this solution from Samsung should work for you.
This app has also been ported to non-Samsung devices by some developer(s) but the Fingerprint unlock functionality does not work on non-Samsung devices yet.
(Mentioning the below content just for the sake of completeness; doesn't answer this question)
- Google Smart Lock for Chromebooks — This is a solution provided by Google to unlock your PC with a fingerprint scanner on your phone. However this only works on Chrome OS (v71+) and not on any other OS.
