Yes.

No, that won't work.  Directional override changes the directional
properties of individual _characters_, so "Hello" will be displayed as
"olleH", which is not what you want.

What you want is to cause _words_ be laid out right to left, even
though normally 2 juxtaposed English words would be laid out left to
right, in the direction they are read.  For that, use the RLM
(RIGHT-TO-LEFT MARK) between "Hello" and "David".  That's one solution
suggested by the ELisp manual.

Why would you need to?  These control characters are supposed to be
invisible (the Unicode Standard actually advises to remove them from
text on display, but it was un-Emacsy, so I left them in).

I suggest to tell what problem are you trying to solve by displaying
the directional controls, rather than asking how to display them.
(And I already answered that question anyway: customize
glyphless-char-display-control.)
