Yes you can define your own projections. Coordinate Systems may have arbitrary
direction, but in the particular case of ProjectedCRS the axis directions are
currently restricted to East, West, North, South, "North along x meridian",
"South along x meridian" - the last two are for polar projections.

I guess it depends on the module. As far as the "referencing" module is
concerned, we use the standard J2SE plugin mechanism: you can declare your own
CRS or projection in META-INF/services directory in your JAR, which is
automatically parsed when needed.

You means for CRS definitions or for data? For data, you have the choice among a
variety of data source and you can use your own (doesn't need to be
JDBC-backed). For CRS, it is possible too but I would recommand to stick with a
EPSG-backed source at least for terrestrial coordinate reference systems.
