Make a female mold for each shape you need. Then you do a lay-up with the glass and resin. When the part(s) are done, trim to fit, assemble, and glass them together into an assembly.
To make the female mold, it's typical to make a male sample part (prototype) from wood, or plaster, or clay or whatever. Then you make the female tool from the sample part.
