I've struggled with this puzzle set by CRUX. Can anyone help with the last 4, all in bottom left corner, please?

18a Dog bites Frenchman-the language! (5) ??M?R Possibly cur(KHER) and
Monsieur(M) making KHMER language?

20a Caesar was so involved with Cleopatra (his empire comes first) (12)
??M?A?I?A?L? Think it must be at least part anagram but best fit
seemed to be COMPATIBALLY.

26a Runs are few and far between (4) ??R?

13d Twenty-ten, poetically speaking (10) ?E?????E?? This contains the first
letter of other three clues hence few letters found.

Thank you in anticipation.

Thank you all, sandyRoe, Claibax, Aquagility and Oldred. You are absolutely correct:3 down was "end of the line" rather than "end of the road" hence all your answers are now a perfect fit.
Thanks again
