When I am in the network of this openwrt router, I am able to resolve the static leases by appending .lan (so that is working fine).
jan@nuc2:~$ ping nuc1.lan
PING nuc1.lan (192.168.2.11) 56(84) bytes of data.
64 bytes from nuc1.lan (192.168.2.11): icmp_seq=1 ttl=64 time=21.5 ms
64 bytes from nuc1.lan (192.168.2.11): icmp_seq=2 ttl=64 time=18.3 ms
but the same ping is not working when I am in the other openWrt network (see here below). Note that the same ping is working when I am using the actual IP address.
mac-jan:nuc2 jan$ ping nuc1.lan

So I would like to configure DNS on my 2 openwrt routers so that it is able to resolve those .lan addresses in the other network.
Yes, or you can make subdomains like home.lan and office.lan. The point being that the two sites have to have different domain names so that DNS requests can be directed to the proper site.
When I am logged on to a server of archer7 network and I do ping mac-jan.lan2 then it doesn't work.
jan@nuc1:~$ ping mac-jan.lan2
ping: mac-jan.lan2: No address associated with hostname
