Updating a Late 2012 iMac to Monterey:

Seems just fine to me. It will work, if is is 21.5 Inch (see the second link below). Just backup first.

Updating the macOS:

Determining which Update(s) will Install:

I. Verify Compatibility:

A. Start Here: Learn About Compatibility and how to Identify your Specific Mac Model - Apple Support

B. How to Verify:

I Reveal your Model:

What is the Model of your Mac? To find out...

1. Go to: Apple menu
2. Click: About this Mac
3. View: Second Line-Down

then...

II. Compare the Results:

See if the Model you found is shown here:

• macOS Monterey is Compatible with these Computers - Apple Support

III. If Compatible:

Back Up your Mac First:  Be certain you Create a Time Machine Backup of your Mac, so that way you can have something to restore your Mac from, should anything go wrong with the reconfiguration.

Back up your data, check the application compatibility table, click here, and if you're referring to the MacBook Air listed below your post, then on the download link for it. A regular MacBook of that year isn't capable of it.

Catalina and above won't run 32-bit software; if you choose one of them, use Go64 as well.
