Just some stupid questions

1. Those can generally both be used to refer to a specific, smaller number of something, but "few" always means a small number while "some" doesn't always. As an example, "some people in the world are women" makes sense, but "a few people in the world are women" does not. However, "some of the jellybeans in my hand are red" and "a few of the jellybeans in my hand are red" both make sense.  2. Yes, the word "you" can have a plural definition and can be used to address a group.  3. It's fairly often that someone will post on this sub asking for someone to chat with to practice their English. All you have to do is ask around on this sub! 

"Some" means roughly any part of a group less than a whole. Most often it's less than 50% but it could mean only "not all." "Few" means a small but plural number. In a group of less than 100 things total, a few would only mean 3 or 4 but in larger groups it would mean less than 10-15%. "Ye" is not used, and most educated people wouldn't know what it was used for historically. But you can use "you" as a plural. "You all" is in common use in some parts of the US (including "y'all") but it isn't formal English.

i would say "you guys" (northeast US) "ye" is never used. we only know it from old songs and the like
