Most of them. Lysosomes, endoplasmic reticulum, golgi apparatus, peroxisome, vacuoles all have single membranes. Nucleus has double membrane to make it less permeable, chloroplasts have membrane bound structures (thylakoid) inside its two membranes, and mitochondria have larger membrane that is folded within the outer membrane for added surface area.
