PCI slots are used for a variety of things, while AGPs are used for only video cards. AGP was orginally invented so you could have a free slot for a video card when all PCI slots were being used. Basically all video cards for PCI slots are very outdated. AGP slots have a lot better selection, though PCI-E have the best. You need some PCI slots, and if you're getting a new computer, or even just a new motherboard, you should get one with a PCI-E slot instead of an AGP slot.

PCI is a general spec which replaced the ISA slots on a motherboard. They are smaller and faster than ISA so it was an improvement. AGP is yet another spec for video cards. A PCI card will not fit into an AGP slot and vice versa. Every several years they have to come up with a new spec to reflect changing capabilities of the hardware. These are just two ways to deal with the changes.

They are two different type slots. PCI (rapidly becoming outdated but still on many motherboards for compatibility) and PCIe (the new standard) can fit different types of cards. AGP is graphics only. For video, if you have the slots, PCIe is slightly better than AGP8 which is better than PCI.
The cards are not interchangable, but you cannot hurt your system, the right card will only go in the right slot.

The AGP is the accelerated graphics port, it is just used for graphics, where the PCI can be used for a wider variety of cards, from modem, to usb ports, to sound cards and so on.
