what's wrong with my plants?

I definitely don't have a green thumb. It's closer to black, kinda like my mother's. I currently have four plants. One, I have amazingly kept alive for nearly 2 1/2 years. Of course, it's one that doesn't require much water or sun, so that helps! I've had my second plant, an African Violet, for about three months. It's on my table, so I see it all the time and sometimes remember to water it. My newest two plants I received as gifts about two weeks ago. They both aren't looking so good! I'm not sure what to do for them--I water them (I don't think too much), but the only place in my apartment that gets good sunlight is in the entryway right outside my door, and it gets really hot there. Any suggestions?

These are geraniums with something else thrown in for good measure. The person who gave them to me didn't know what they were, either. See those little buds? They were there two weeks ago, too . . . and they've never shown any signs of opening.


These are some kind of impatiens. The tag said they need lots of sunlight--not ideal for my apartment! They're looking pretty sickly!
