If $(X,tau)$ is a paracompact, is there a topology $tau'supseteq tau$ such that $(X,tau')$ is still paracompact, and $tau'$ is maximal with respect to $subseteq$ and paracompactness?

Any discrete space is paracompact, since the family of singletons is locally finite and an open refinement of every open cover. Put $tau'=mathcalP(X)$. Then the discrete space $(X,tau')$ is paracompact, and $tau'$ is maximal with respect to inclusion and paracompactness.
