Can it be used to connect a surround sound receiver without an amp. pre-out port-by way of the front speaker terminals- to a second amplifier?

The short answer is no. You will be taking the high level output from your first amplifier to the low level input of your second amplifier. At the least this will result in distorted sound. At worst you will damage one or both amplifiers.

can this selector be used to select between an amplifier and a surround Receiver?

Yes, for left and right. I switch my main pair of speakers between one amp for my turntable and another amp for surround which also uses that same main pair in addition to a center and a sub. In other a pair of speakers can switch between two amps.

What size banana plugs fit into the connectors on the back? They must be minis like 3 or 3 mm. Standard banana plugs seem to be too big.

When unscrewing the banana plug the inner hole can accommodate up to 4 mm plug .

can you switch both pairs of speakers on at same time with either amp 1 or amp 2 iow - 1 amp into 2 pairs of speakers?

Either amp can access the speakers, however, you must choose which speaker you desire as both speakers cannot be on at the same time. Only one or the other. The same rule applies to the amps as well.
