We ask you to please thoroughly read the VEX Robotics Comeptition Nothing But Net Game Manual and to please review the Q&A Usage Guidelines before posting in this forum. Specifically, please quote the rule or definition that your question is referring to.

The answer to your question can be found in <R12> which is quoted below:

@VEX Robotics Competition Nothing But Net Game Manual

<R12> A maximum of one (1) VEX Y-cable can be used per Motor Port of the Microcontroller or Power Expander. (You cannot “Y off a Y” to have more than two (2) motors controlled by the same Motor Port.)
a. Teams using the VEX ARM® Cortex®-based Microcontroller can only power one (1) 2-wire Motor per each of the two 2-wire motor ports on the Microcontroller. It is illegal to “Y” off a 2-wire Motor Port.
b. Teams may not “Y” off a Motor Controller 29

But this is for per port, is there are total number restrictions? like theoretically can you use 6 y cables for 6 ports?

After you read through the rules, you will see that there are no other specific rules about Y-cable restrictions. Thus what you have described is legal.
