running wires

I'm running a few new circuits in my 1966 rambler, through the main level floor joists. two 20 amp 12-2 cicuits, one for a new 1/2 bath, and one for future use in the garage also one 50 amp 6-3 circuit for our kitchen range. I've read bout securing the wire along the studs, but nothing about doing so when you're running it through the joists. Is there any such requirement, or do you only secure it once the wire makes the turn and travels along the side of the framing members?
Also, could someone explain to me the requirement about fire retardant caulking? Does it affect the number of wires passing through a hole?
Thank you

Running through holes in the joist is considered securing it. Nothing further is required.
