I have 4 cameras set up to watch my house but when I connect to the host name only one shows up even when I use different host names. How can I view all my cameras?

Assign a different port to each camera. Each port can only be forwarded to one internal device.
Specifically how you would go about this depends a bit on your router's capabilities. If your router allows forwarding one external port to a different internal port (for example forwarding port 80 to port 81 on an internal device), then the simplest approach would be to set up the forwarding similar to this example:
port 80 -> 192.168.0.10 port 80 port 81 -> 192.168.0.11 port 80 port 82 -> 192.168.0.12 port 80 ...etc...
If your router does not support forwarding one port to another (i.e. you can't choose a different internal port for the destination device), you would have to change the webcams' listening ports. One could listen to port 80, the next could listen to port 81, etc. The port mappings should then look similar to this example:
port 80 -> 192.168.0.10 port 80 port 81 -> 192.168.0.11 port 81 port 82 -> 192.168.0.12 port 82 ...etc...
The difference between these examples is that in the first example you don't have to change the listening ports on the webcams, but in the second example you do.

You had to get your cams each to listen to different ports, e.g. 8081, 8082, 8083 and 8084. Then you had to set up for forwarder rules on your router, one for each camera/port, each rules pointing to the internal IP address of that camera. Now you can start calling your cams from outside:
yourname.dyndns.org:8081 -> 192.168.1.111:8081
yourname.dyndns.org:8082 -> 192.168.1.112:8082
yourname.dyndns.org:8083 -> 192.168.1.113:8083
yourname.dyndns.org:8084 -> 192.168.1.114:8084
In case your router supports port translation with forwarder rules, all cameras can listen on the same (internal) port.
yourname.dyndns.org:8081 -> 192.168.1.111:80
yourname.dyndns.org:8082 -> 192.168.1.112:80
yourname.dyndns.org:8083 -> 192.168.1.113:80
yourname.dyndns.org:8084 -> 192.168.1.114:80
Edit: Arrgh, too many "helpers" are underway. :x (no smileys available?)

You would need to set each camera to run on a different port and then configure your port forwarding to point each port the appropriate camera.
Once that is done, you would need to reference the port number in your URL to connect to the camera.
