To every when do I have to drain my battery and charge it all the way up to 100%?

You do not have to drain the battery nor charge it to 100%. Just leave the computer plugged in when convenient to do so. Stop trying to micro manage the power/charging system. The MacOS handles that task very well.

It isn't harmful to use the MacBook Air while it is charging.

Also see th following option described in Charge the MacBook Air battery - Apple Support

Optimized Battery Charging: This feature helps to reduce the wear on your battery and improve its lifespan by learning your daily charging routine. It delays charging the battery past 80% when it predicts that you’ll be plugged in for an extended period of time, and aims to charge the battery before you unplug. You can change this option in Battery preferences.

There is no way to make battery health stay at 100% but the following may be of interest: About battery health management in Mac notebooks - Apple Support

Is it safe to use the laptop while charging? like browsing/streaming a movie from Netflix and so?

Yes

It should not cause a problem. Also, you can activate optimised battery charging to reduce battery ageing.

If you want, to get the extreme battery health, you should install this app: https://www.macupdate.com/app/mac/63002/aldente, called AIDENTE. It helps you to decide at what percentage it stops charging (you can keep the charger connected all the time, basically using it as a desktop).
