Yes. The sign priority is used to determine the sign that will be
displayed in a line.

Yes. The sign_getplaced() function returns all the signs placed in a buffer.
If multiple signs are placed on a line, then the signs are sorted by
their priority.
If two or more signs have the same priority, then they are sorted by their order
of placement (the last placed sign takes precedence over the older ones).
