I have read that a block contains several transactions.
An attacker can forge fake a block.
The blockchain is safe because the system will choose and keep the longest chain.
So the fake block will be lost.
This is great but what happens if my transaction was included in the fake block?
Let's suppose I am buying a car. Should I wait for 6 confirmations to be sure? That would mean that I have to wait one hour!

An attacker can forge fake block.
Yes, but an invalid block would be rejected by all other participants that see it, and not relayed. Thus, such a block has little to no impact.

A transaction is a signed payment order to the Bitcoin network.
As long as it remains a valid instruction set to the network, it will be tracked and distributed by network participants to include in a block. From the perspective of nodes following the best chain, being included in a block that is not part of the best chain is equivalent to not being included in any block at all. Thus, an invalid block including a transaction has no impact on any nodes that recognize the block as invalid–they still consider the transaction unconfirmed and they will continue to consider it for inclusion in another block.

It is also in the memory pool (mempool) of pending transactions at other nodes run by more honest people and will be included in a new and valid block in the normal way.

Yes.
There are faster payment methods for Bitcoin - e.g. Lightning Network (LN) and arguably perhaps escrow services. But they have their own trust model and characteristics you need to understand when using them.

The fake block is ignored and you have to wait until the next block, 2 blocks, 4 blocks, or 6 blocks, depending on how many confirmations the miner wants to be mined. But, if you are using Lightning, this can't happen unless you are taking out of lightning. The invalid block will not be added. If the miner will mine your block (ignoring other factors such as transaction fee, willingness of miner to fill block fully (this is not a problem anymore), average block time (if the difficulty hasn't changed recently enough, only really a problem if it goes down, it would help if it's predicted to go up), and the number of transactions sitting already), there is already a 62% chance that the confirmation will happen in 10 minutes. Although you have to wait, just be patient.
