is the block headers are transactions informations (the sender the receiver/time/amount .. etc)

No. The block headers contains the merkel root which contains the transaction hashes which are assembled. They do not contain specific transaction information persay.

so the validity of a transaction depends on the Bitcoin Blockchain Algorithm Rules (Mathematically) is this correct ?

Protocol rules: https://en.bitcoin.it/wiki/Protocol_rules.

so the pool alse could be called as huge Node, is this correct ?

Pools should be running a node, probably not a reference implementation though. Pools do not have to run a node explicitly, the only thing that they need is the transaction information, previous block hash and all that. These can be easily obtained from various sources.

Thanks a million for your help, so helpful thanks a lot again
