Out of everything you've mentioned, I would summarize as follows:
1) Avoid the 2.4. Its a fine engine, but it was never paired with a good transmission (other than the 5-speed stick), and really didn't go in many very good vehicles.
2)2002+ Rams with the 4.7 or 5.7- EXCELLENT vehicles. If you can afford it, go with a 2008 or newer. They fixed a lot of pesky HVAC glitches with the later ones, and gave the 4.7 an extra 80 horsepower starting in 2008. Both of those engine choices are typical Chrysler bulletproof engines, with the advantage of being paired with an equally bulletproof 545RFE transmission and a solid chassis.
3) Ram 1500s with 5.2 and 5.9. They were very good... in their day. If you can find one with low miles and in good condition, it wouldn't be a bad bet. The 46RH / 46RE transmission was OK, being based on the old A727. But the O/D tacked onto it was not as strong as the rest of the transmission. The 5.2 and 5.9 Magnum had some issues with the lower cover on the intake plenum leaking and letting oil mist get sucked into the intake stream causing extreme pinging, but that's fixable with a revised lower plenum cover gasket from Hughes (and I think it was fixed from the factory around 97 or so).
So in short, I would recommend the newest Ram with a 5.7 or 4.7 that you can get.
