An infant under 2 travels free as a lap child, you just need to pay whatever YQ they dream up for the airline concerned.
I think that other people have done this particular routing so it is valid.
Can't help with the 4 seats though and you may have to look at other airlines other than SQ for this one to get the number of seats that you need.
