After replacing the water pump, the engine is still overheating

Hello,

Your question got cut off in the middle of the sentence and I don't see any picture/video uploaded either.
Please let me know the details.

An engine can overheat due to a number of reasons. It could be because of a stuck closed thermostat, bad radiator, inoperative cooling fans, water pump, clog in the system.
Here is a helpful guide:

Let me know of any questions.

Thank you.

The upper radiator house looks like this. It was coolant pouring out of it while I was adding it.

Looks like the part on the radiator is broken, as you can see the edge is gone. So, the fix would be to replace the radiator, unfortunately.
You can put the hose back on with the clamp, but there is a good chance it will come off due to pressure. As there is usually an edge/lip on the plastic part of the radiator to keep the hose from slipping off (see picture below).

Let me know the engine size and I can province you with the radiator replacement procedure.

2007 Ford Fusion, 6 cylinder and thank you for your time and patience!

No problem at all.
See attached for the radiator replacement diagrams.
