Colour is British. Color is American. There are a fair few words that the Americans drop the 'U' from. This is all thanks to Noah Webster. He came up with the American way of spelling things because he thought the English way was rubbish and to complicated. It's also thanks to him that words like 'centre' in English, is spelt 'center' in American.

I would like to speak English.

I'm sorry to say that it's just another of those grammar rules that makes little sense. For most words ending in F or FE you change it for VES. But as always some words have to be different such as roof, chief, belief and chef all change to plural by adding an S.

It's a bit of a tricky one. Yes you can do it either way, but at the end of the day you need to see how it fits into the rest of the sentence. As someone else has pointed out, it needs to flow. Try reading it out loud in the complete paragraph to see how it sounds.

An autocrat is a ruler with absolute authority. So that would be like some of the 3rd world nations where there is an army general running the place how he wants with no elections. So you would say that they have an autocratic leadership. Is that any help to you?
