Lesbian
A homosexual women.
For the first picture (far left) I searched "butch lesbian" because that's what most people think lesbians are. Or vice versa, in which just because a woman decides to present herself in a certain way, that she's gay. I don't think that anyone should assume anything and people should be able to express themselves in anyway they feel comfortable.
Lesbians want to be men?
Lesbians who look more masculine or "butch" do so because that's how they feel comfortable. This is merely a form of gender expression and does not relate directly to their sexual orientation.
A classic lesbian symbol
A common stereotype is that there needs to be a "man" in every lesbian relationship. This is almost never true.
