This is overstated. It is extremely unlikely (not impossible, just extremely
unlikely) to induce noise that would be audible on an amplified speaker wire.
The concern is more legitimate with line-level audio, video, phone, etc.
I was wondering if :
Would be ok running speakers wire in parallel to other speakers wires inside pvc electrical conduit or smurf tubes inside the walls/ceilings? or would create any issues (noise)?
No problem. It's done all the time.
Also, can you run Cat 6 or HDMI cable in parallel with speakers wires or each other? If so, would be best to run the cables and wires in parallel at a specific distance from each other?
It is definitely a good idea to keep speaker wires away from other much lower-voltage signals like audio, HDMI, ethernet, phone, etc.
You should treat speaker wire more like you would high-voltage line, you want to keep all the rest of your signals away from it if possible, don't run them all together for long distances, etc.
