I assume this means you're trying to change the bearings without
removing the crank.
Do the conrods in whatever order is convenient. I find it easiest to do
them two at a time, so you aren't trying to turn the crank with loose
rods flopping around and possibly denting a journal. Before or after
mains doesn't matter, but do the mains one at a time.

The journal is the shiny part of the crank that rides on the bearing
inserts. Merriam-Webster : "the part of a rotating shaft, axle, roll,
or spindle that turns in a bearing"

As Dave said, support it by always leaving some of the main bearing caps
in place.

Broken timing chain tensioner ? Mangled remains of thrust washer ?
Swarf dropped into engine by DPO ?
Chunks that big almost certainly have not been through the bearings, so
they have to be either pieces that broke off inside the engine, or
foreign objects.
Good Luck
