Mercury and Venus have no satellites. Then earth has moon (synchronized orbit). For Mars - both its satellites (Fobos and Deimos) also synchronized. Analyzing other planets is hard - too many satellites. Maybe someone knows percentage - all of them synchronized or which ones are not synchronized (if just a few ones are not synchronized). All 4 largest Jupiter satellites are also synchronized.
This is not really known; while the rotation period of most of the larger satellites is known, and they're mostly synchronized, for the smaller ones it's harder to determine and they're less likely to be synchronized:
One conclusion is that, other things being equal ... a large moon will lock faster than a smaller moon at the same orbital distance from the planet. ... A possible example of this is in the Saturn system, where Hyperion is not tidally locked, whereas the larger Iapetus, which orbits at a greater distance, is.
Wikipedia has a list of synchronized satellites and 'suspects', if you want to investigate further.
