My friend sent me some bitcoins "he says so"
But I want to confirm whether He has ever send any amount to my address ever and if he did
Then how many times and when and list of all the transactions.
Is there any way I can know this?

about:"how many times and when and list of all the transactions."
You can check txid, and there are details there, you can see them.
