comment Movement of the satellites of the planets . . .
Well, Mercury has an inclination of ~7° and Venus about 3.4°; if that's coplanar, then the answer is no. Especially smaller moons can have very high inclinations.

With coplanar, do you mean the inclination? No, not necessarily; for instance the smaller jovian moon can have inclinations of >160°. See en.m.wikipedia.org/wiki/Moons_of_Jupiter

comment Do planetary surface temperatures change in unison in a solar system?
Uh, if I apply this formula to earth and it's distance, I get -24.6°C... is this approximation ok-ish and the difference due to the athmosphere?

comment Why do Jovian moons fade when transiting Jupiter's shadow?
If you search for "jovian moons umbra" at scholar.google.com you'll find lot's of historical observation reports dealing with this questions. For instance: Birmingham, J. "Correspondence-Jupiter." Astronomical register 10 (1872): 94-95. adsabs.harvard.edu/full/1872AReg...10R..94B
