Apart from the little plays in the Juvenilia, hte only play of JA's that I know to be in print is Sir Charles Grandison , edited by Brian Southam. It's a very slim book, with a VERY high pricetag, and I was only able to have a quick look at it, not take it away an dreally read it.

It is a juvenile piece, and like many of them , a spoof of the original, having very little in common with the plots, or even the characterisation, as far as I can see.

If the other plays still exist, I think they must not be in published form..but I'm not sure of that.
