Hello Zoe and welcome to NGA
Your plants are both what are called "tender" succulents, meaning they cannot thrive in temps below about 10 Celsius (50 degrees Fahrenheit)
They will love a fast draining soil, I use some pumice and add to the potting soil, if you don't have that you can buy cactus soil
The plant on the right is an easy to grow plant, can't remember the name it'll colour up in more light. These probably need to be indoor plants for you, in the brightest window you have
Cheers
