 This type of technology, Directed Acyclic Graphs (DAGs), can be implemented on cryptocurrency, or it is a different solution from blockchain? This  concept is not clear for me.

I know that DAGs are a solution to ease the transactions, but I am not sure how it can be implemented, do we need to create a new crypto having it, it can be added to a crypto or it is not into the blockchain technnology?

IOTA is a top10 marketcap coin which doesn't run on a blockchain, but on a DAG.
It's not blockchain technology

Iota is a centralized cryptocurrency which uses Proof of Work+ proof of authority (the coordinator node).

Decentralization is a possibility in the future for iota, but not their main goal. Iota needs free and fast transactions for it to work on internet of things (IoT). And DAG allow iota to do it.

There are no miners and each transaction confirms 2 early ones for free.

DAGs differ from blockchains in that they  store transaction history in a vastly different way.

On blockchains transactions are ordered by concrete checkpoints -- that is, the blocks that confirm a transaction. DAGs don't care all that much for transaction ordering as long as they are not double-spent -- which also seems to be the biggest challenge for DAGs so far.

While most blockchains mitigate double-spends by applying PoW, PoS or other proof-of-resource schemes, DAG-based cryptocurrencies so far rely on centralized, trusted entities -- eg. Iota's coordinator and ByteBall's witnesses.

So far I'm not aware of any decentralized DAG-based cryptocurrencies; I'm not sure whether the need for centralization really is an inherent property of DAG-based cryptocurrencies though.

DAG are different from blockchain system. I'm not sure on how DAG system runs. You could try using the blockchain system which is more easier for transaction and safer.

Easier? safer? actually is totally different.
