Your program will not get any CPU for the duration.
It is safe, only your messages arrive but do not get  handled (no CPU for you). In case of a timer this may get problematic for your program logic.

Yes, the difference is that these functions wait also (or only) for external events you requested.

Sleep only suspends the THREAD which it is called from, not the whole application. Sleep is not a method (it is not bound to any object) but rather a procedure. Its use is safe virtually everywhere.

in a delphi application it only makes sense to use Sleep in a new thread. if u use sleep in e.g. form1 procedure then the app will appear to delay during that Sleep. user will notice app lock if moves window accros dewktop. the window freeses during Sleep
