intel-corei7-64 is a MACHINE name used by meta-intel and doesn't mean
that it is specific to i7. You can use this machine value for Atom.

I'd request that you try out the latest 4.14 on warrior (or 4.19)
instead of 4.14.18 from rocko and report back if you see issues.
linux-intel doesn't have a 5.0 recipe since it's only based on LTS
kernels. You can switch to using 5.0 linux-yocto kernel though when
using warrior branch:
PREFERRED_PROVIDER_virtual/kernel = "linux-yocto"

linux-intel carries Intel specific patches and backports that aren't
part of stable/mainline kernel.

There is no difference. If you compare the branches, they should be
same.
