Network adapter and Network adapter 2 correspond to e0a and e0b, which will be used for the cluster network. These should be "host-only" since they are internal to the cluster.
Network adapter 3 and Network adapter 4 correspond to e0c and e0d. These could be bridged, depending on what (if any) network your computer is connected to. I would use the "nat" network, and assign IP address from the nat VM network to node management and cluster management. You can get these by looking at your IP settings for VMNET8 in ifconfig/ipconfig on the host. If you use bridged, assign address from the network you are bridged to.
Both nodes should be identically configured from a network standpoint.
