Should I design seperated frame sizes like this
to show developer better understanding for the responsive design ?
Or just made 1 responsive design?
I’d make one responsive, turn into a component, hand over with a separate spec where your team can see various sizes / breakpoints
However, Figma does not cover all things that make design responsive. In CSS we can change elements order, flow direction etc. In this case I usually create few variations of the same component. And document required behavior, which is the most important piece here
I get it, so you think I already done in right way?
I do several variations for the same components according to different frame sizes too.
