Really need help on my setup and XR15 remote

I have an Insignia Fire TV and Yamaha soundbar. Here's what I'd like to be able to do with my XR15 remote and I need to know if this is possible.

1) Control Power for the TV

2) Control the volume up/down for the soundbar

3) For the TV inputs, I plan on using the Insignia remote

4) For the Apple TV, I plan on using the Apple TV remote

Are 1 and 2 possible with the XR15 remote?
