The second game (The Lion, The Wizard and the Wardrobe) is a lot like the first. Same engine, same gameplay, same humor.
I found the puzzles to be slightly less intuitive in the second one, but overall it still works.
The third game (Simon 3D) suffered from all the problems of early 3D conversions – ugly blocky graphics, unpolished controls and gameplay.
The fourth one (Chaos Happens) I know very little of, but my wife has played it and said it was OK. More like the first two, but with 3D graphics (way better than in Simon 3D). I think she claimed it felt rather short.
