I thought I had one jade plant but turns out, I had 2. Does any of them seem like there's any trouble?

Had this plant since April. It receives direct sunlight upto 11AM. I water it once every week & the temperature is 40-45°C. I noticed few yellowing leaves & found out on Google that thin yellow leaves mean I'm giving it less water. What should I do?
