I.
The direction of induced current in a coil is simply decided by using lenz law which states that cause oppose the effect
Now as the current is going upward and is decreasing so that due to this the magnetic field of this wire is come upward in the loop A so that due to this Loop will try to induce current in such a way that it will try to reduce the effect of this upward magnetic field hence in this loop the direction of induced current will be in clockwise direction .
Similarly in the loop B the direction of wires magnetic filed is into the page or in downward direction so that due to this the current induced in this loop is in anticlockwise direction.
II.
Since induced current dependency is solely on the magnetic field imparted on it and the area of the loop so that here as the loop B has higher area so that induced current will also be higher in loop B as compared to the loop A.

Not sure if there isn't enough information since the left loop
is increasing while the right loop is decreasing flux. Or is it
clockwise? I would love an explanation.

The figure shows two parallel loops of wire having a common
axis. The smaller loop (radius r ) is above the larger
loop (radius R) by a distance x >> R.
Consequently, the magnetic field due to the counterclockwise
current i in the larger loop is nearly constant throughout
the smaller loop.
Suppose that i, the current in the larger loop is shut
off, and decreases at the constant rate
di/dt.
