Im not sure what you exactly mean with 'normal confirmation'. But a transactions 'receives' the first confirmation after getting included into a block.
Each mined block after this first confirmations adds another one (assuming the new block is mined upon the chain which included the block with the transaction).
2-3 confirmation are enough for 'standard' amounts. For larger amounts 6 confirmation are recommended.
Thats not completely correct. Most block explorer show the outputs of unconfirmed transactions as 'unspent' too.
The 'safety' of arrival is 'measured' in the amount of confirmations a transaction got.
Or if someone else uses those UTXO in a transaction.
As long as the block containing the transactoin is in the longest valid chain and the coins 'have not been moved yet', they will stay 'unspent'.
