Change a font weight

Question

I want to create a new font family with \newfontfamily{\rb}{Roboto} from here:
https://fonts.google.com/specimen/Roboto?subset=latin&preview.text=Hello&preview.text_type=custom#standard-styles

I want to write a few words with weight 300 for example, it is possible?
I saw this question: Set the "font-weight: lighter/ bolder"

But there are two things:

I want to change it on the specific words, and not overall...
so I'm looking for kind of a command like \textbf or something like that.
I want to use numbers (the number of the weight).

Thank you!

Does this answer help? For your font, the weight 300 version is probably called either Roboto Light or Roboto Light 300. — Willie Wong, Mar 29 '21 at 16:17
Probably yes... @WillieWong - It's not what I asked for the answer says, but it helps somehow... :) Thank you! — heblyx, Mar 30 '21 at 14:17

Roboto weight 300 is called Roboto-Light.ttf, so, using the recommended standard weight series names (see texdoc fntguide), you can load it using fontspec as {l} series and then set up a \textl{} command to use it.

As to using numbers in command names, you can use Roman numerals (\textiii):

Or alternatively, set up a generic command that takes a numeric option, which in turn calls the matching \text... command behind the scenes.
