That looks to me to be fiberglass. While it is possible that it also contains asbestos, I would doubt it. Only way to know with certainty is to have it tested.

Also, you have mold growing in the fiberglass, and mineral deposits on the outer sheath. Something has been leaking on this for quite some time, and that concerns me more than the potential of asbestos.

Doesn't look like it, but there could be an asbestos-containing liner surrounding the pipe.

Looks like newer fiberglass with reinforced paper. It's all gross from getting wet over and over. Might want to have an inspector verify that there are no suspect layers in there.

What does the fitting insulation look like?

Thanks all!! Seems like mostly not concerned but might want to get outer layer tested and check out mold growth.
