I need help to answer my questions about my Natal/Birth chart

My Midheaven is heavily aspected with squares... what does that mean for my career?

What does it mean to have my Jupiter (Pisces in H1), Saturn (Taurus in H2), Uranus (Aquarius in H11), Neptune (Capricorn in H11) and Pallas (Pisces H1) retrogaded?

What happens when there is a polarity between my Sun (Virgo) and Ascendant (Pisces)?

I have critical degrees on both my ascendant and descendant.
Along with my other planet placements; Moon Libra 13, Uranus Aquarius 9, Neptune Capricorn 29

Is it bad to have my Chiron in Scorpio and the Eighth house?

A better understanding about my Part of Fortune (Aries in H1), Vertex (Virgo in H7) and my asteroids?

What does it mean to have no placements within my 4th, 10th and 12th houses?

Is my moon considered to be an unaspected planet?

How well can I achieve my North Node (Virgo in H6)?
South Node (Pisces in H12)
Sun, Mercury, Venus, Vertex - Virgo, all in H7
Jupiter, Pallas and Ascendant - Pisces, all in H1

Is it possible to have a cusp North Node (Virgo-Leo)?

What does it mean to be born on a cusp of Virgo-Libra?

I don't have any planet placements within my 4th, 10th and 12th house.
