3.5L, no. 2.7L, maybe- should be 5w30 5.7L, yes. Needs to be 5w20.
Depends on year and engine size and climate, could be 5w20, 5w30, 10w30, or 15w40Depends on year and engine size and climate, could be 5w20, 5w30, 10w30, or 15w40
5w30 or 10w30

2.4L uses 5w20 2.7L uses 5w20 3.5L uses 10w30
if it's not the right kind, then YES. I'm pretty sure a 87 Bird takes 10W30
Ford recommends the use of 5w20. In fact, they push 5w20 for all the Modular V8's, and even back dated the older Modulars to use 5W20. They tested the 5W20 Motorcraft oil enough to recommend useage for all the Modulars. That being said, if you have cold winters run 5W20 or 5W30. Because of the engines tighter tolerances, and the OHC design, a thinner oil cold will be a better choice so it flows to the upper cylinder heads quicker. If you live in a hot climate, 10W30 wouldn't be a bad choice, but the 4.6L was designed to use 5W30/5W20. I run 10W30 in the summer, 5W30 in the winter. Hope this helps.
The 5.9 uses 10w30. The 5.7 uses 5W20. The v10 uses 10w30.
