All of your constraints should be able to be accommodated:
it doesn't matter if they are linear, convex or not, etc.

Unless you working with exotic things like Bayes logic or Pareto 
optimization,
but we're working on supporting Bayes and Pareto better in OptaPlanner.

Just add a negative constraint for the number of employees that don't 
work at their primary location.
If you want it to be "fair" between employees, count it per employee and 
square it.
Depending on your business requirements, you might want to add it as a 
medium constraint (instead of a hard one or soft one). See 
HardMediumSoftScore in docs.

Not sure what you mean. But instead of trying to specify how to optimize 
("sorting employees"),
specify what to optimize ("prioritize employees based on ranking").
