Note that the export / import support is specifically limited in scope:
it is only designed to support moving content between instances with
"identical" software configurations (including Zope version, add-on
Products, etc.) It happens to work, sometimes, to import a .zexp from a
slightly different configuration, but there are no guarantees.
It sounds as though the .zexp files you are trying to import contain
objects whose classes are defined in add-on products which you do not
have installed. Debugging that problem is likely to be a
trial-and-error process, identifying each product (preferrably with the
same version as used in the original instance).
Depending on your needs, it might be advisable to outsource the problem
to somebody in the community having experience with the particular
products used by the old instance.
