First of all you're misusing the term "hosts"as Virtual Machine's are called Guests not Hosts.
Only edit the file if VMware Fusion is closed and the target VM is shutdown, not suspended!
If your dhcpd.conf file is truly as you said "(below is my config)" you need to place and static assignments at the end of the file after "####### VMNET DHCP Configuration. End of "DO NOT MODIFY SECTION" #######", not at the top of the file!
