It's not going to be down to a specific module - it's the way you program/configure it.

Pairing isn't mandatory.

Hello @Andrew Neil 

Thanks for replying

So that mean BLE doesn't require pairing even for a first connection ( for the first time )? 

Another question please, with your BLE Module can i connect at the some time to many other modules and collect data in the same time ? 

Thanks

Correct.

That depends on the module, and the application in/using it.

Plenty of modules are available which can do that. It requires more resources, so they won't be the cheapest ones...
