Implementing Figma Designs in Webflow Automatically

there is no "automatic" way of implementing a design yet. You'll have to reproduce any designs from Figma into Webflow. Our component library will get you about 75% there though - maybe more - it just depends on how many changes you've made in Figma.

how can I do it pls?

You'll have to learn Webflow and build your design. https://university.webflow.com/courses/figma-to-webflow

i'm not very advanced in Webflow, but can you suggest a plugin, or something to convert those things from RELUME to Webflow pls?

at this time there is no plugin to convert from Relume to Webflow.

But your colleague told me that there was. Here

No, Emily said that you can use that plugin to sync variables but that plugin was built by webflow not us. And the code that the plugin generates does not follow client-first - thus my original answer. Hope that clarifies it.
