As it stands in iOS 6.1.4, the current limit for Bluetooth Low Energy devices is 10 simultaneous CONNECTIONS (at least on the NRF8002 chipset). Although the BLE spec says it can in theory have an infinite number of connections, the connection will time out when you try to add an 11th device.

As for the pairing table, I've previously had two additional a2dp devices in my pairing table(not connected) and 10 current BLE connections as the maximum. So that is a total of 12 devices in the pairing table on an iPhone 5 running iOS 6.1.4. You could probably have more devices listed in the pairing table, but the one definite is 10 connections is the current max.

The bluetooth specification allows more than one device to connect at a time, but it's not straightforward, as it is dependent on the type of device and the service profile it provides.

For example, you can have a bluetooth keyboard, mouse, and headset connected at the same time, and an A2DP (Advanced Audio Distribution Profile) device to stream music, but you can't have two devices that performing the same service profile connected at the same time.
