I have a similar setup at home with host declarations and a set of DNS 
servers being pushed to the devices. On all of my Android devices they 
seem to be taking these settings normally. So it might be worth 
double-checking the client devices before doing such masqueraded setup 
(which could end up being overkill).

Off the top of my head, I can think of the Private DNS settings in newer 
versions of Android overriding the DNS settings pushed by the DHCP 
server, as well as any VPN connections. Perhaps one or both of these are 
active and interfering?

I don't know if this is relevant, but in my dhcpd.conf I also have the 
options for domain/search and DNS servers to use above the host settings.
