1. Can I wake up my android from sleep mode through a trigger from a PIR motion sensor?

What Android is this?

Your Arduino, of course.

2. Can I wake up another Arduino in the same room from a transmission from that Arduino?

Don't know. How would they be connected?

3. Can I supply the sensors through the Arduino while it is on sleep mode?

You do not "supply" sensors through the Arduino so i do not know what you are trying to say.
