Yes, you need to enable notifications of the wanted characteristics of the motion service.

You'll see from the service description table you've linked to that some of the characteristics sends preprocessed data in a specified C99 type and units.
Be aware of the Fixed-point representation of floats, f.ex 12Q4.

I found a way to connect to thingy board. Now I am trying to read the orientation data from thingy. I found a table named "motion service" from this website, but I dont know how to use it. Do I need to subscribe to that service?

There's not really any detailed documentation for the android app.

I suggest you start reading the code at line 685 of https://github.com/NordicSemiconductor/Android-Nordic-Thingy/blob/master/thingylib/src/main/java/no/nordicsemi/android/thingylib/ThingyConnection.java

It is the function you call to connect to a specific Thingy device.
You can have up to 20 concurrent BLE links with the S132 SoftDevice, but you'll have to consider what throughput you need from each thingy. The 52832 running on 2mbps PHY can get you about 700kbps on a decent link.
