Yes you can as long as the cam that you are calling original is a roller cam.
If it is just inspect the lobes on the camshaft real good and close.
Not necessarily. However it would be advisable to replace the lifters and timing chain while you're in there. This is also a great time to upgrade the pushrods and rockers.
lifters
That would depend on how many valves each cylinder has and the location of the camshaft.
This is an answer in general not just for a Renault. In general a camshaft does not wear out very fast. A camshaft should last for the entire life of the engine. If you ever take the engine apart for a rebuild you could inspect the camshaft then for wear.
Yes, but you must keep the lifters with the cam they were originally used with.
NEED to??? No. But the question becomes, why are you replacing the camshaft? You should always replace the lifters when replacing the camshaft. A worn camshaft usually indicates that there will be other wear as well, but if you just want to squeeze a few more miles out of the engine, you might be able to get by with just replacing the cam and lifters.
Either the cam follower arms, or the so called "lifters". No camshaft makes DIRECT contact with the valve stems!

To put the camshaft in takes a few minute. To strip down the engine to the stage where you can fit the camshaft and then rebuild it can take several hours.
1. Make sure it is the lifters and not loose wrist pins. 2. Check the camshaft for wear. When the lobes wear beyond the take-up tolerance of the hydraulic lifters, clicking is the result. Your favorite garage may have an instrument to check actual pushrod movement against what is called for by the published camshaft lift.
The camshaft of a 350 Chevrolet engine is held in place by a retaining plate or the lifters. The retention method depends on whether the cam is a roller or flat tappet design.
