Question Securing multiple electrical lines?

What is common practice or code when running new electrical lines in a home(15 amp/20 amp) in a basement that feed up to the 1st and 2nd floor of a home?

Is there a rule on how many wires can be run down the same floor joist overhead? In other words, If I need to run 10 new 15amp/20amp lines, can they bunched together and secured to the floor joist overheat safely, or is there a rule on how many can be together? And what is the rule if these wires need to cross a metal gas line?

Running parallel cables in the same joist space is not an issue.

Cables should be secured with staples or other approved fasteners maximum of 4.5' apart. Staples are normally rated for 2 cables max.

No more then 4 - two wire cables should be tightly bundled together (like with zip ties) for longer then 24" or derating factors come into play.

Crossing a gas or water lines is not an issue and can be in direct contact.

Stapling a lot of cables to the side of a floor joist is a lot of work.

A relatively new product called a cable stacker is a perfect way way to run multiple cables with minimum fastening effort.
