Agent 1 is getting acd call and agent 1 is transferring to the call to agent 2; agent 2 is getting connected to the call but status is not changing agent 2 is getting another call.

When a call is transferred to an Agent it is no longer an ACD call. The call is instead on the user's queue and can be assigned more calls.

Transferring directly to an agent loses certain statistics, also. If you want to maintain a queued environment, create an internal transfer back to an IVR or workgroup queue. Let it find the appropriate SME for the call. You will have better stats; be able to change skill levels; and the use of the new workgroup will change your agent status and block further calls.
