A #1 copper wire with an insulation rating of 90 degrees C is rated at 140 amps.

Yes, as long as it has the necessary ampacity for the load and is properly fastened at each terminal. For example, we have a 4/0 aluminum cable feeding our 200 A subpanel 120 feet away.
Three feet clearance is needed in front of electrical service equipment.
It depends on where the sub panel is situated. If the panel is under the same roof as the main distribution panel then no ground rods are needed on the sub panel. If the sub panel is in a different building then a ground rod might be needed. There has been an electrical code rule change on this subject. Check with your local electrical inspector before installation so that it is done correctly.

Depends on the size of the sub-panel in that garage. If you are installing a 60 amp sub-panel 400 feet away from the main service panel then use AWG # 4.

Re Question with the voltage that you will be using.
it is the plastic panel to the left of your feet on the drivers side and to right side of your feet on the passengerside.
A #8 copper wire with an insulation factor of 75 or 90 degrees C is rated at 45 amps.
It depends on where the sub panel is situated. If the panel is under the same roof as the main distribution panel then no ground rods are needed on the sub panel.
