I need help setting up Two Reference power conditioner 20Is on the same circuit

I have TEN Anthem Monoblocks M1s I need protected for my Home theater. I have 20amp GFI Recepticle Circut.

Three Questions:
1. Can those two Furman 20Is be plugged into the same circut two outlet wall 20amp receptacle and work in sync with having my monoblocks split between the two Conditioners?

2. The Furman Reference power 20i only has FOUR “High Current, Ultra Low Impedance, Linearly Filtered AC Power” Outlets. I only have TWO i20s for 10 mono amps. This leaves me with 2 Left. I don’t know what to do. The other eight outlets on the Furman 20I are “Discrete Symmetrically Balanced, Linearly Filtered AC Power” Outlets.
Can the monoblocks work in sync with the high current outlets on the two Furmans PC as long as they are BOTH plugged into the same 20amp wall circuit?

3. Final question, The remainder two monoamps: can I plug three monoblocks into an extension strip to be plugged into the High Current outlet? I was thinking 3 amps powering my side/rear surrounds.

I’d appreciate some input. Thanks! -Eric
