lets say it reached this block number and my etc coins were there when it reached. and this wallet is supporting the fork. and I have the private key of this wallet.
can I just move my etc out of there after this block reached? and how do I will receive the clo coins, will it be there (in this particular wallet)?
If you have wallet that supports both then yes. If not anyway clo coins will be available to you when you want to move them out as long as you have the private key.
