Just place all the updates in a directory and install them with;
rpm -Fvh *.rpm
Except for the kernel rpm never use -U or -F always use:
rpm -ivh kernel-version.rpm
The kernel-headers rpm use -U or -F. The kernel-source rpm it is up to you. You can use -U, -F, or -i depending on whether you want to also keep your old kernel source or not.
