Are the Nikon Coolpix L120, 310, or 610 interchangable lense?

I have one person telling me they are and one telling me they aren't - but I'm not sure, I'm not a technical person when it comes to cameras and I'm new to cameras also.
They said I should consider this as my new camera, but I want a camera similar to this one with interchangable lense if this one doesn't have this feauture.

Any suggestions?

Camera Comparison? Help?

I'm looking for a new camera, and I don't know if I'm confused or what happened, haha.My friend recommended the Nikon Coolpix P150 for me. When I searched it up to find more information, mostly Nikon Coolpix p510 has come up. I've looked into both, and what I find with Nikon Coolpix p150 is the same pictures of the camera as the p510. When I look online for pricing and reviews, all that I can find is the Coolpix p510 and not the Coolpix p150. Basically, what i'm asking is:
Does the Nikon Coolpix P150 even exist? If so, how come I can't find any information? And also, if it does, which is the better camera and why?
Please answer, thank you. (:

My camera keeps auto focusing?

I have a nikon coolpix s220. I try and take a photo and it just sits there and auto-focuses, then it is like it is trying to take a photo, but there is no flash and there is no picture in the memory of it taking one.It just flashes AF in green writing on the screen. I have tried changing the resolution to the poorest and the best. I have changed night, day, party, close-up, whatever. I have tried zooming and and zooming out. I have tried being outdoors in the sun, changing where the light is.

I have only taken about 30 photos with this camera.Do you think it is shot? My last camera only lasted about 30 photos too. I am pretty disappointed if it is shot because all I want to do is take a photo.

No, I can't find the manual. However, it is a fairly basic model with not that many options of changing things.
Added (1). Edit. Thanks BriaR for clearing that up.To me, AF stands for atrial fibrillation, however, it seems like it has that too. Hahaha.
