DLLs no, EXEs yes. You can load dxe files (the go32 variant of a DLL)
using the dxeload unit.

Free Pascal is 32/64 bit, so the answer is no, you cannot build 16 bit

No, since it can use virtual memory there is not need for overlays.

Overlays were an extremely limited way of having virtual memory, though
there were very usefull to squeeze things in 640K. I doubt your current
computer has a 640K memory limit, therefore you have no need to use such
