Hello Emilie,
How to specify atoms, residues, etc. in the command line is explained on this page, and there are many examples:

The part about model numbers and residue numbers is here: 

I don't know what you mean by "highlight":  you can select, color, display, change display style, etc. ...  so for example, the following commands would select those residues by number and display them.

select :175,248,273,282
display sel

You can use the Actions menu on that selection (or other commands) to change style and color, add labels etc.

Then to turn off the selection, menu Select... Clear Selection, or command: ~select

You might be interested that we have Chimera "image gallery" entries of P53 showing some of the mutation positions:

There are more examples of using residue numbers in tutorials, for example:

I hope this helps,
