YES -- that's corrosion, and it can greatly reduce the conductivity of
the braid.

Sure. it means your coax has gotten wet.

If it all looks like that, YES. I'd do some more inspection first.
Water gets into coax either at connectors, or at tiny breaks in the
outer jacket, look for damage and for poor waterproofing.
And I would be a lot more careful with what I bought to replace it, and
I'd also be VERY careful about proper installation of connectors, and of
waterproofing all the connections.
