Have you looked up each verb in several dictionaries? If not, please do so, then come back to us and tell us what similarities/differences you find. Also, please use each of the four verbs in a sentence so that we can see what you're trying to say.
I wasn't suggesting that you look them up in an English-Spanish dictionary. I meant that you should look them up in several English dictionaries - they give definitions in English, rather than a translation to your own language.
You can search multiple dictionaries at One Look. You might want to bookmark that site and use it regularly.
