Some of the hobbits (archetypally Delta rational) say he is a "queer fellow" and dislike his seeming unpredictability and mysteriousness, but others (archetypally Delta irrational) enjoy his company and see him as an intruiging and fun visitor.
I think Frodo is IEE and Sam is SLI. Bilbo is probably SEI. Merry and Pippin are probably an Alpha Extrovert pair. Boromir was probably SLE. Aragorn is a pretty clear EIE. Faramir is probably IEI. The elves are generally Beta/Gamma; I would say Galadriel is ESI, Elrond probably LSI.
As for the Silmarillion, I think a few typings go almost without saying:
Feanor: SLE
Fingolfin: EIE (<3 favorite Tolkien character for sure)
Finarfin: IEI
Manwe: LSE
Mandos: ILI
Turin: SLE
Niniel: IEI
Thingol: ESI
Ingwe: LSE
Races
Noldor: Beta
Teleri: Alpha
Vanyar: Delta
Others I'm not entirely sure on:
Finwe: ESE
Fingon: SEE
Maedhros: EIE
Caranthir: IEI
