What can I do if my iPad 2 apps are not compatible?

you mean buy new one?

Acquiring a newer (used, refurb) or new iPad model, yes.

what should I do with the one I have?

You can use it as a music player, or for whatever else you’re using it for now, or can recycle it, or whatever else.

A decade-old iPad won’t have much residual value.

Apple is offering free recycling, but not any trade-in value.

For recent iPadOS, you will need to replace that iPad 2nd gen (2011-2014) with a newer or new iPad.
