I would say you should be level 50+. You could be lower but with better food.
XP is not calculate when you kill a monster, but every time you hit it. You get XP for every damage point you inflict. In the case of magic spells, you also get a basic magic experience, just for using the spell. I am not sure about ranged.

Relatively.It's weaker than a greater demon, but stronger than an imp.

I beat a lesser demon on a pure at level 34 combat, you can do it with a level 61 easily.
You can defeat a lesser demon with regular weapons and armor, if you are low level, I suggest that you either get stronger first, or if you have a strong ranger skill, attack with a distance with a crossbow while wearing ranger armor.
A decent Crossbow or normal bow would do the trick.
