Im sorry; its not clear what you're asking. In your pic I see a datacenter configured but no cluster yet.  You should be able to make your cluster and move whatever resources (hosts) you want into it.

Yes thats right.  You will need two hosts of the same CPU level and two Storage datastores that are accessible by both for witness files for failover but yes you are on the right tracks.

Prior to enabling you'll need to create a vmotion port group on each host.  Typically you should put this on a segregates vlan (doesn't need to route) and enable port for vmotion

You can do that, and create the Cluster, and enable DRS, but nothing will happen, unless as @paulsolov has stated, you enable vMotion on a VMKernel Portgroup. (e.g. VMs will not MOVE!).

Therefore I would recommend you Enable vMotion, and TEST vMotion before Enabling HA and DRS.

I have created the cluster.
I need to move the two already existing hosts into that cluster.
I am attaching screenshot with the network configuration of one of the two  hosts.

Is it enabled for vMotion?

You will need to click Properties of the vSwitch, and select a VMKernel Portgroup, and Click tick vMotion.

You also need to *think* about your Networking design.

Just randomly click and ticking boxes, is not best practice for Cluster setup, your VMware vSphere environment is only as good as your networking design, bad network design, you will experience issues!

It's recommended to have a dedicated network for vMotion, at least two nics, and seperate vSwitch!

and nics, for vMotion should be setup as per teaming is in my iSCSI document, see the override failover part, with two nics

HOW TO: Add an iSCSI Software Adaptor and Create an iSCSI Multipath Network in VMware vSphere Hypervisor ESXi 5.0

Just drag and drop the hosts into the Cluster, of Highlight Cluster, and select Add Host...

thanks. When i drag and drop i got the message that the host cannot be admitted to the cluster's current enhanced vmotion compatibility. POwered-on or suspended vm's on the host may be using CPU features hidden by that mode.

That is true.

have you defined an EVC profile ?

Are your hosts the same ?

e.g. same generation of processor or different ?
