Update from 10.9.5
I currently have version 10.9.5 installed and I want to update it to the latest version. How do I do so, and if it is not compatible, what can I do? I have a 2011 MacBook Air.

How to upgrade to macOS High Sierra - Apple Support
Go to Section 4 and click on Get macOS High Sierra,
this will redirect you to the App Store High Sierra download page,
it should now say Get or Download.
Before upgrading make a full back up of your Mac.
Check that third party apps you use have updates available for the new OS.
Check that your printers/ scanners etc have updated drivers and software available for the new OS.
Connect your mac to your router via cable rather than rely on WiFi.
Do not use your mac while it is downloading
and do not use any other devices that share the same internet connection.
The App Store Purchases does not show previous purchases/ downloads of macOS's
Sierra, High Sierra, Mojave and Catalina if you have ever purchased/ downloaded them.
Older Mac OS X's El Capitan, Yosemite and Mavericks are still displayed.
If you have a mac running Mojave or Catalina the App Store no longer
shows any previously purchased/ downloaded mac operating systems.
Back up your data, check your applications for compatibility, and download High Sierra. Your computer isn't capable of Mojave or above.

You only have to download it and Apple assume it's "installed" even if you didn't. Ignore the App Store label and either retrieve the installer you downloaded once, or download it again from the Purchases tab of the App Store.

Just Upgrade:
If it is incompatible, then get you always have the option to get a new Mac. 32-bit applications are incompatible with Catalina. So, contact the developer if you were to upgrade, making sure they have a 64-bit option for you.
Thank you, one more question. According to mac store High Sierra is installed already but that is not the case. Is there a way to un-install it?
It's referring to the installer. Choose Applications from the Finder's Go menu and run or delete it as desired.
