Now that is a big question. There are 151 Pokemon in Pokemon Blue version and most of them evolve. About 24 Pokemon have no evolutions or pre-evolutions (as of the Kanto Pokedex) and 5 Pokemon are legendary and thus do not evolve. A total of 20 Pokemon need a special stone or to be traded to evolve, leaving about 103 Pokemon that evolve when they reach a certain level (excluding Pokemon who are fully evolved).
You'll find that Pokemon who have two evolutions will evolve from level 10 - 19. A good example would be Charmander to Charmeleon. Charmander evolves into its stage 2 evolution at level 16. The only exception to those levels are the Bug-type Pokemon who generally evolve to stage 3 before reaching level 10.
Pokemon who only have one evolution will evolve just a bit later at level 20 - 29. Rattata to Raticate is a good example - it evolves when it reaches level 20.
Stage 2 evolution Pokemon will evolve into stage 3 evolution Pokemon near level 30 - 40. The only Kanto Pokemon who really do this are the stage 2 starter Pokemon. Wartortle evolves into Blastoise around the level 36 mark.
Some Pokemon are exempt from these rules. Rare Pokemon such as Omanyte, Kabuto, Dratini and Dragonair evolve at later levels. Both fossil Pokemon must reach level 40 to evolve and Dratini evolves into Dragonair at level 30 while Dragonair evolves into Dragonite at level 55. These (and the bug Pokemon) are the only Kanto Pokemon who are exceptions, however.
Do remember that many Pokemon will need to have an elemental stone used on them to evolve and thus do not need to reach any specific level. Very few Pokemon will need to be traded to evolve. For more specific information on a Pokemon and which level it evolves on, search the internet or Wiki s for what you need.
Levels vary from level 6 all the way to level 55. Several pokemon evolve at similar levels but a majority evolve at different levels.
They all evolve at different levels
Most Pokemon evolve by levelling up. It would be a waste of time to list all of the ones that evolve at certain levels.
Pokemon that evolve with levels have certain levels, all of them are different. Some don't evolve by levels, and either have to be happy or use an evolutionary stone.
Pokemon evolve at different lvls and some might not evolve by lvls or at all. Some will evolve by items or by trading or by taking really good care of it. Lengendary Pokemon will not evolve.

It depends on which Pokemon it is because they all have different evolving levels.

No. All pokemon currently have a maximum of 3 levels of evolution.
36. infact, all the Pokemon evolve at their normal levels, but you need to beat rayquaza to evolve- you cannot evolve in a dungeon
um, which Pokemon is holding the stone? because all Pokemon evolve at different levels. be more specific
All Pokemon evolve at different levels, and some evovle under special circumstances (like Milotic and Riolu). You need to be more specific.
