After I create a instance in the ec2 cloud, I only see the private IP/DNS and public DNS but no public IP address. Is there a way to activate a public IP address in the console? (not the elastic ip address).
The public IP is part of the public DNS record, ie:
ec2-x-x-x-x.compute-1.amazonaws.com
Here, the X's would be the IP address you're looking for.

I have two instances in AWS where we have public ip and private ip for one instance and the other instance has only private ip.
Both are in the same VPC and same subnet. However I’m not able to access/ping the public ip from the instance 2. I can ping/access it using private ip. But how can we achieve it using public ip.
I have tried using the icmp rules in the security group but still not accessible.
I did not use elastic Ip address. I assigned my public Ip address change other ip Adress. After I change my public address in Route 53 . but it will not work.
When I create a machine on Amazon AWS it always comes with Public and Private IP.
I need to have the public IP directly on the server's network card.
It's possible?
I don't think this is possible. What AWS does, is a mapping from public IP address to the primary private IP address using network address translation (NAT). They actually don't assign a public IP address to EC2 instances.

I created an instance in Amazon ec2 and deployed. Now I am able to access my applications using the public dns. My default public dns is like ec2****compute-1.amazonaws.com. How can I change this to some Other Public Dns.
Get an elastic IP address from amazon
assign the elastic IP address to your instance through the aws management interface
Point your domain to your elastic IP address using your registrar's DNS tools

Is it possible to assign Elastic IP Address to my instance without changing the public IP address?, i need to Transforms my public IP address to be Elastic IP Address
Yes. It is possible. You can access your instance with Both Elastic IP as well as Public IP Address. But remember when your EC2 instance restart at that time its public IP may get change so people preferring to use Elastic IP Address.
Hope this Helps !
Using Elastic Network Interfaces it is possible if you started the instance in a VPC. You can assign the Elastic IP to an Elastic Network Interface which you can then attach to the EC2 instance. EC2 instances in VPC can have multiple ENI. If you assign an EIP directly to the EC2 instance (classic or VPC) then the public IP changes to the EIP.
When you associate an EIP with an instance, the instance's current
public IP address is released to the EC2-Classic public IP address
pool. If you disassociate an EIP from the instance, the instance is
automatically assigned a new public IP address within a few minutes.
In addition, stopping the instance also disassociates the EIP from it.
