It is important to approach this question with respect and understanding. Lesbian sexual activity, like any sexual activity, varies greatly among individuals and couples. Humping, or dry humping, can be a form of sexual activity that some lesbian couples may engage in, but it is not exclusive to lesbians and not all lesbians may engage in this activity. It is crucial to remember that all sexual activities should be consensual and practiced in a safe and respectful manner.

Some lesbians do interact with each other sexually in this way. It is because it is pleasurable for the one recieving.

No, not all of them. Lesbians are loyal too. Were not different creatures. -.- Just because we are lesbians doesn't mean we magically don't cheat. We are human beings.
Without the introduction of a male to the situation and the transfer of sperm to where it can meet the egg somehow, a woman cannot get pregnant. So two lesbians on their own cannot each other pregnant, no.
