>From your diagram here, it looks like you don't have a loop - it looks like
Sw B is plugged into Sw A, A to C, then C to D in series. If this is
accurate, then you don't have a loop and won't have any problems.
As far as STP works, each switch will send out BPDUs every two seconds on
all interfaces. If a switch receives two BPDUs from the same switch on two
different interfaces, it will start the election process and you'll have a
few seconds of downtime (not exactly sure how much - 15 or so?). But again,
from this diagram it doesn't look like you have a loop, so you should be
okay.

The network looks like this:
------------ ------------
| Switch A |-------------| Switch B |
------------ ------------
| |
| <------ This is link I plugin.
------------ ------------
| Switch C |-------------| Switch D |
------------ ------------
So if switch D is then plugged in, will it start STP negotiation on the
port even though the switch has already booted? Or will one of the
switches randomly discover the loop after the link is already forwarding
traffic and disable it's interfaces?
