The intracellular receptors differ from membrane receptors based on their location. Membrane receptors are usually on the plasma membrane but the intracellular receptors are found inside the cell.

Among others, yes, they serve as membrane receptors.

membrane receptors are proteins that would be synthesized on ribosomes on the rough endoplasmic reticulum

Receptors of protein hormones are present in plasma membrane but for steroid hormones no membrane receptors are needed as they can enter cell membrane , mobile receptors pic steroid hormones from cell membrane and carry them to nucleus .
