That would depend on the year. If it has the multi displacement system(2005+) or variable valve timing(2009+), no. Using anything other than 5w20 will turn on the check engine light.
Yes, you definitely can use that.
If you do the check engine light may come on with a code for improper oil used. If that happens the multi displacement system will be disabled. Use 5w30/5w20, whichever is correct for your model year.
A 2004 Hemi uses 5W30, conventional or synthetic.
5w20, does not have to be synthetic.5w20, does not have to be synthetic.
5W20. It can be synthetic, conventional, or a blend.

Either will work fine.Either will work fine.
No
