Amend Lighting in Photos

I have 13 photos that need to be improved with the following:
- Grey sky to be replaced with a blue sky. It needs to feel tropical but needs to look realistic at the same time. Sadly the day the photos were taken the weather was moody, storm clouds with rain.
- Plunge pool of water to be bluer to reflect a blue sky
- Green jungle foliage to be more luscious green to reflect a blue sky
- Interior photos to look brighter not so dull.
Please can you confirm if you can improve 13 photos within an hour? I have attached 3 of the photos to give you an idea, as I am sure you understand due to these being raw files I am not able to upload more than 3. All 13 photos are of the same room and balcony with plunge pool just different angles.
