[JR West Rail Pass - Kansai Wide]

Hi,

I would like to buy the JR West Rail Pass - Kansai Wide. 

https://www.westjr.co.jp/global/en/ticket/pass/kansai_wide/

 

My questions are:

1. I will be travelling from Kyoto to Uno. Are there any trains that are not valid for usage under this Rail Pass?

2. I will also be travelling from Uno to Osaka. Are there any trains that are not valid for usage under this Rail Pass?

3. Can I use this Rail Pass for the The Rapi:t Airport Express from Osaka Namba Station to Kansai International Airport?

Thanks
