There is no current Mac that will run these applications, anymore.
Pagemaker is old and no longer exists. Adobe bought out Macromedia (the original developers of Freehand) and killed Freehand, after one or two more version upgrades, to kill the competition between Freehand and Adobe's own vector application Illustrator.
Depending on how old your father's Macs are, you maybe able to find newer, but still older Macs that may still run these outdated applications.
The very last versions of PageMaker for the Mac and FreehandMX were problematic on newer Intel Mac models running under OS X 10.6 Snow Leopard which is the last version of OS X to support older PowerMac (PowerPC) coded software.
You may may have to look for the last PowerPC Macs, either the last models of G4 or G5 PowerMacs that will run the last universal version of OS X, 10.5 Leopard.
