Questions for a devout muslim?

Hi I'm a Pakistani Muslim. Actually I was born in Canada but raised in America but anyways do Muslims really pray 5 times a day because I tried and i is pretty hard. Also I don't know arabic so is it okay if I recite my surahs in english. I know a couple surahs in Arabic but when I recite them during prayer im not sure of the meaning and my mind is somewhere else. Also I just got english translation of the Koran and is it okay if I read that instead the real version? Also at Jumah the Eemom says a speech and then we all bow are heads and raise are hands and then the eemom says stuff in Arabic and then the ppl say ameen what is he saying?
