Yes.  Files marked with `C' are not affected.

If you want the copies to be marked with `*'
(instead of `C') in the target directory then
set or bind `dired-keep-marker-copy' to `t'
for the copy operation.  Otherwise the mark
used is `C'.

You can.  But you need not unmark files that
are marked with another mark, if you want them
marked normally (or in some other way).

You can instead use `* c' to change marks of
one kind (e.g. `C') to marks of another kind
(e.g. `*').

The prompts for this use `read-char', so it is
very quick (no need to hit `RET').

This is an important feature, usable for more
than one purpose.  You can use it, for example,
to save a set of marks and then restore them
later, or to merge (union) multiple sets of
marks.

To save and restore: change `*' marks to some
new (unused) char, e.g. `+', and later change
the `+' marks back to `*'.

Dired has lots of handy things like this, some
of which are not known too well.  Another
handy one is `M-DEL' (aka `M-<backspace>').
It unmarks a particular mark (for all files
listed in the buffer).  Just hit `RET' to
remove all marks, of any kind.

(`RET' is read by `read-char', just like any
other char.  In this case, the char is Control-M,
aka carriage return.)
