Hello Mr. Victor , since the hydrogen and halogen can be placed anywhere since its not a syn addition if there were 2 chiral centers you would draw 4 stereoisomers for number 2 16:30 ( the cyclopentane ) ?

Yep
If the chiral center existed before hydrohalogenation , would it still be factored in the number of stereoisomers? Like if there were 2 new chiral centers made and 1 there before hydrohalogenation would there be 2^3 stereoisomers or 2^2?

also if we consider old chiral centers why is that?

the possible stereoisomers that are valid products are only the absolute configurations of the new chiral centers you create through hydrohalogenation right?

This is too broad of a statement/question. You always need to consider the structure of your substrate. Is it chiral or enantiomerically pure? Are there any carbocation rearrangements that may create or erase chiral centers? Are we making or destroying any elements of symmetry? Always consider the starting material and don't try to come up with the "universal solution" -- it doesn't exist.
at 16:30 can't you do a ring expansion as well?

That’s a possibility, yes.
