"Który mężczyzna jest stary?"

Translation: Which man is old?

[TFG]

The old one

[Jellei]

Seems possible in some contexts, added.

Why is this "ktory" and not "ktora"??

[Jellei]

Because "mężczyzna" is a man, so he's masculine, and the form of "który" has to match.

Why does the version of man change i.e mężczyźna mężczyzna? Thank you

It depends on the role in sentence that is realized with different cases - variations of the same word. Different the role in sentence or preposition before noun, different is the used case. Sometimes You can treat cases as noun combined with preposition in one word e.g usually in construction done x „with y” this „done y” is translated with Instrumental.

There is no such thing like mężczyźna. Mężczyzna is nominative singular. Nominative plural is „mężczyźni” - probably this is what you meant.

Can someone please explain the difference between Które, Który, Którzy, my head is about to explode. So confusing, as they all mean "which".... which one do I use in which situation - and why - pardon the pun.

[alik1989]

Those are different declensions of the same lexeme.

Jellei or any other kind moderator: Please explain why stary and not stare - I'm on phone app and dont have the laptop hints at hand. Dziękuje.

Adjectives inflect depending on the case and gender of the noun they refer to. Mężczyzna is masculine nominative, so you have to choose the adjective accordingly.
