Feel free to read the documentation: https://threejs.org/docs/#api/en/math/Vector3.angleTo
It’s not so clear what you mean with “popup”. Use raycaster, and if it intersect a mesh, then show an html-element with information.

is it possible to render the pop up https://react.semantic-ui.com/modules/popup/ like this with the vertices that we have if it satisfied the condition near to the intersected vertices

You decide the units of your own models. When importing models from others, hopefully they will have included a specification of what a “world unit” means in their model, which you can convert into a suitable scaling factor that you apply to the model to get it into your units.

You can try to use something like that: https://threejs.org/examples/?q=css2#css2d_label
