You can't get there from a basic hominid. You might be able to do it with genetic engineering, but you wouldn't have anything compatible with a human after that.

The problem is:

• Are around 1.5 times stronger than humans while having a lither frame and higher muscle density and other adaptations for strength. Increased ATP production, Denser bones to handle stress etc.

and

• Greater stamina and speed than humans.

Muscle density is pretty much identical in all hominids. Changing that would require a lot of evolutionary backtracking, and that never happens. You can increase strength by changing joint lever ratios, but stronger = slower and weaker = faster. That's a law of physics.

As for stamina and speed, they're also somewhat contradictory. The faster you run, the less time you can run for, due to energy usage and atmospheric drag. You might be able to achieve stronger and faster by being bigger, but bigger and heavier means that it takes more energy to run, which tends to reduce endurance.

• Can enter torpor though it is highly risky

Primates don't do this as far as I know. Evolving it might be tricky, though it need not be risky.

• Need to eat more

Predators are often able to swallow large amounts of meat. Alternating gluttony with starvation is easily achieved.

• Larger eyes closer to that of a Neanderthals
• Pointed canines and incisors

These shouldn't take too much to evolve.

• Is able to interbreed with humans

This is the trickiest bit. As long as the chromosomes match reasonably well between the two, and there haven't been any incompatible genetic changes, it should work. However, allowing interbreeding is a barrier to speciation. These elves are going to have to be isolated for a good few hundred thousand years to achieve these differences.

So, despite all the 'easy to achieve' things, you can't evolve these elves from humans at all. You're going to have to keep muscle density the same as every other mammal, and change other things like lever ratios and/or total muscle mass.

Alternatively, ditch the science-based requirement and go with fantasy instead. It's a lot more forgiving.

Muscle density is pretty much identical in all hominids. Changing that (by which I mean changing the Actin/Myosin proteins of the muscles which makes them work) would probably require a lot of evolutionary backtracking or a generational disadvantage, and that never happens.
