Arbok can not evolve into any other Pokemon. Hope this helps.
Each Pokemon is different and not all evolve because they have reached a specific level (some evolve due to high friendship, being traded, getting an item used on them, etc.). Some Pokemon that evolve through level will evolve between levels 10 and 20, and some may not have their first evolution until the late 30s. Also, not all Pokemon evolve. If you want a very accurate, satisfying answer, you will need to ask about a specific Pokemon.
I have gotten it to around level 43 and nothing yet, I can only imagine it will evolve at 45 or 50...
It is a pretty decent Pokemon team, but not excellent. You should at least evolve the Dragonair into a Dragonite, which, although it takes a very long time, is worth it in the long run. Shuckle is practically useless in the Elite Four, and is nothing more than a distraction for healing your other Pokemon. All of your Pokemon should at least be on level 43-45 to have a fighting chance, too.
