Forum:Question regarding Angel 07 and activating abilities

So i've been wondering this for awhile, regarding Majesty's Fiend and cards like it (Angel 07) that say monster's effects cannot be activated this only refers to monsters like Barrel Dragon and Snipe Hunter correct? and for BLS Envoy of the Beginning it would not let him use his first effect but allow him to use his second effect?

Im just wondering what the guidelines on this would be, and if yall could link me to the different types of effects monsters can have?
