I got a second hand MBA m1 and i got it on 94% maximum capacity with 21 cycle count. It looks quite weird with those number of cycle count. Can you give me some tips to use it without losing the maximum capacity. And one more thins, can I use the laptop after 80% of maximum capacity?
The battery is degrading pretty fast like 4-5% in 20 minutes

What you see is not unusual. It is impossible to not to lose maximum capacity because of charging cycles and simply age. No rechargeable battery will maintain its factory capacity over time.
Best to do is just enable "Optimize Battery Charging" and let the machine learn your usage and optimize charging based on that. Micromanaging the charging is basically a waste of time. Batteries are consumable items in the Mac just like in any other device that uses batteries.
As for being able to use the Mac if the maximum capacity drops below 80%, the only thing that happens is that you end up with less working time while on battery. When you find you no longer have sufficient time to work while on battery, that is when you replace the battery.

This sounds to me that you are talking about battery run time in this statement and not battery capacity which is something else entirely.
First, check Activity Monitor and look for items using a lot of CPU or doing a lot of disk activity. You can then narrow down the offending app and take appropriate measures. Often the app may simply need to be upgraded/updated to be compatible with the current operating system. One other thing on this topic, when you first get a Mac, a lot of stuff will be going in the background for some time initially for things like Spotlight, Time Machine, and even apps. After the initial period they will start using much less CPU time and therefore battery use.
Second, display brightness can consume a lot of power. Try setting it to a lower brightness if possible.
