Can I connect 3 wireless routers as follows:
Router 1 dhcp enabled; 192.168.1.1
IP range 192.168.1.2 - 100
static addresses assigned only to local computers

Router 2 connected by ethernet LAN to LAN from router 1
192.16.1.101
dhcp disabled

Router 3 connected by ethernet: Router 2 LAN to router 3 WAN
dhcp enabled. IP 192.168.2.1 with range of 2 -100
no static addresses assigned

My intention is for router 2 to NOT to do any dhcp but I want router 3 to hand out IP's to users connected by wifi.

You only want one router to be handing out IP addresses.
Unless you are really, really careful, Router #1 and Router #3 will give out the same IP address to two different systems.
Confusion abounds.

1 router can hand out enough internal...

1 router can hand out enough internal IP addresses.
Don't try to force this to be otherwise.
Configure the 2nd and 3rd as just access points.
Let Router #1 give out IP addresses.

Yes, that is exactly how to do it if you want double-NAT on router 3 and to avoid any chance of 1 and 3 competing to hand out addresses as they are on different subnets.

Router 2 is properly on the same subnet and not in the DHCP range of 1 so everything should work properly.

Double-NAT allows the Wifi clients to share their own network and still have internet access, unlike AP isolation which gives Wifi clients ONLY internet access. Of course double-NAT can cause some issues with some programs which will require manually opening ports.
