OK. Let's see what different theories predict about the Higgs-particle spectrum.
What | 0+ | 0- | +-1 |
Unbroken Standard Model | 1 | 1 | 1 |
Eaten by Z and W+- | 0 | 1 | 1 |
Low-energy SM | 1 | 0 | 0 |
Low-energy MSSM | 2 | 1 | 1 |
Low-energy NMSSM | 3 | 2 | 1 |
CP-even neutral: 0+
CP-odd neutral: 0-
Charged: +- 1
MSSM = Minimal SUpersymmetric Standard Model
NMSSM = Next to MSSM
There's an interesting curiosity about the MSSM Higgs masses. A parameter they depend on is m(A), and if it's greater than about 200 GeV, then the particles "decouple". One of them, a neutral CP-even one, stays around 100 GeV and acts much like the SM Higgs particle, especially if m(A) is large. The others get masses close to m(A).
It's that light one that was most likely recently discovered. I can't find any LHC limits on heavy MSSM Higgses, however.

BTW,
First three-year LHC running period reaches a conclusion | CERN press office starting a 2-year shutdown.
