Are these getting the right sunlight?

I’m very much not a plant expert, I just wanted to try having real plants for once, I have a snake plant (right, whit pot) and a zebra plant (left, yellow pot). I water the snake plant once a week and the Debra plant once every 2 weeks. Am I giving them the right care?
