Answer 2

Maybe "observant" works here? I don't know that it reflects your "pick up on things quickly" though.

observant (adjective)

good at watching and listening : good at noticing what is going on around you

careful to follow religious teachings or customs

Answer 3

If you want a noun, quick learner or, more old-fashioned, quick study. Usage: She's a quick study OR she's a quick learner.

Answer 4

Other possibilities:

• Quick-witted man,
• A man sharp as a tack,
• Man of keen/sharp/alert intellect/mind,
• Man with a vivacious spirit,
• Quick/swift thinking man.
