Conditional formatting in SharePoint lists using JSON

I have my conditional formatting working if I only refer to one number. As can be seen in the image below if the cell I want to format has the number "1" in it the formatting works.

I would like the same formatting to work if for example the number was less than "2" or between 3 and 5. I've tried several options with starting with "=if...", but it either breaks the conditional formatting or doesn't make a change. I have been able to find an example that matches the attributes.

Full disclosure the conditional formatting continues so I can apply different colors to other individual numbers. I'm hoping the if I resolve on the set of numbers the others will follow the same framework.
