There are a lot of questions here, and we recommend you get started here on the MultiChain website:

We have installed the multi chain in 2 server one is  Wiredtree and another one is Amazon AWS server.

Using putty we have installed the multi-chain and created a node.

We are facing connection issue.

Error code -5 means RPC_INVALID_ADDRESS_OR_KEY an invalid address, Public Key or Private Key was passed as parameter..

How to fix the error and what is the reason for this error?
You would need to show the full output of the API call you made so we can understand what went wrong. But we recommend starting from the API documentation which will probably help guide you here:

We have rectified the invalid address key error.  We have created two nodes and checked the send / receive transactions.

How own coin and wallet will be created and integrated to multichain?

How to integrate multichain to my application?
Please take a detailed look at all the developer documentation on the MultiChain website, which covers these topics in depth.

You can execute commands from the shell level in PHP - exec() and download what returns multichain.
