Meniscus means the curved upper surface of liquid in a glass tube.
For colourless liquids we consider upper meniscus whereas in case of colour liquids we consider lower meniscus.

Because the other tube has large length so the water would not rise.

Because capillary action depends on cross sectional area not on length.

If area in reduced then height will raise otherwise not.

The water will rise and form a bubble of a greater radius. According to the formula
hr=constant.
hr=constant.

Because adhesive force is high in capillary tube than insufficient tube.

There are no effect of reduce or increase the capillary, liquid adjust in capillary due to gravity and cross section area.

The insufficient tube (large tube) will not allow the water to rise.

Because in small area adhessive force between water and glass dominent than the gravity.
