The answer to "is there a PrC in 3.x that...." is almost always 'yes.' There were just so many, something has to be close.The only one of those PCs that I think could be built in 3E is the last one, and (unless there is some sort of cleric-archer Prestige Class in a splatbook that I haven't heard of) his clericism would be fairly weak.

Doing melee control with a polearm in 3e is nearly effortless - the equivalent of Threatening Reach just for picking up a polearm. Proficiency, Combat Reflexes, maybe Improved Trip and you're there. A fighter level or two is all you need (and you don't really /need/ it unless you're impatient to complete the feats quickly), self-buffing makes him very potent, all the other CoDzilla goodies are on tap, and, as a Dwarf, fighter is even your favored class.*a dwarf fighter-cleric polearm melee controller, who is also pretty handy with his artefact mordenkrad Overhwelm;
A lot of that is flavor. The sorcerer class is very amenable to customization via spell choice, so anything you might picture probably has some close spell analogue, even if it's True Strike or Tensers Transformation or some other self-buff to stand in for your martial arts.*a drow chaos sorcerer who conjures up bursts of light, blasts of fire, and wind and thunder (and is able to fly on the winds he summons), who draws power from the Abyss via his cloaks of demonskin and the strange runes inscribed on his demonskins and the inside of his eyelids, who is also trained in drow jujutsu (monk multiclass to do damage in a burst after a hit, and an at-will melee basic attack with his off-hand dagger), and who is a member of a strange Corellon cult (and bears Corellon's divine boon);
Ritualist would, of course, map to wizard, so probably a wizard for lack of the Invoker class, or, as you say, a Mystic Theurge. With all that cult salad she's got going, maybe even an ur-Priest. She'd be an Assimar instead of a Deva, presumably.*an angelic (deva) invoker who is the rebirth of a human wizard, a cultist of the Raven Queen, Ioun, Erathis and (perhaps) Venca, a master scholar and ritualist, and who can also conjure seering divine radiance - and whose ritual book is possessed by a Book Imp sent by Bane and Levistus to keep watch on him;
A tiefling paladin is doable, I suppose. The STR vs CHA issue is one all pallys face, of course. Magic can make up for a modest lack of STR.*a tiefling paladin of the Raven Queen, aQuesting Knight who is neither especially strong nor athletic, but whose strength of character and devotion is manifest - to both friends and enemies - in everything he does, and who, when combat comes, is able to strike with the strength of ten;
Since the 3e ranger is already a caster, little need to actually multi-class. Your 'favored enemy' bonus models the 'curse,' (as I'm sure quarry does in 4e). No worries.*an elven ranger-cleric, who bolsters his allies with healing and calls down the curse of the Raven Queen upon the enemies he hunts.
Sure, mechanically, those are going to vary a lot in practicality, ease of build, and effectiveness - 3e gave you options, not balance - but each concept should be quite possible.
