Redline and Motul make group 5 oils. And possibly the german castrol. Group 5 are an ester based synthetic oil.

Amsoil Series 3000 5w30 HDD has a heavy dose of group V as well. Both the AME 15w40 and the HDD are a blend of PAO group IV and Esters V. I think that most of the high end synthetics have to have a blend of each as they have slightly different seal characteristcs. One swells while the other shrinks.

Most synthetic motor oils, whether their base is group III or IV, use some group V in their formulation for the benefits they add.
A straight group V motor oil would not be desirable.
Some of the group V's are exellent for compressing natural gas or propane because they don't mix with petroleum.
Others are used for additives
some make good gear oils
Depend on your proposed use
