No, it isn't possible for two Macintosh environments to run simultaneously under A/UX 2.0.1 or A/UX 3.0. Only one Macintosh environment is allowed under A/UX. When the "mac32" or "mac24" process is invoked, it actually starts up the "startmac" or "startmac24" program to create a Macintosh environment. Then the Finder in the System Folder will be executed. This operation is running under Macintosh Toolbox File Manager control; it isn't a re-entrant type of program.
Note that A/UX is capable of supporting Macintosh File Sharing (in A/UX
3.0) and AppleShare CLIENT functionality. The AWS 95 can run AppleShare Pro.
