<<I read somewhere that the tag position within a record is always defined,
it is the first element always, right? not sure what's its size, I assume
it is an address to someother tag related information somewhere else, so its
size is also known, right?

There is no such requirement, in fact there is not even a requirement
that the tag be in the record value at all, and there is a perfectly
reasonable implementation which avoids this (although I don't think any
Ada 95 compiler uses it!)
