Since your weight remains constant, the only variable is the area. Pressure is the ratio of Force to Area, implying that the larger the area the smaller the pressure and vice versa. Since lying down translate into occupying a larger area than when standing up, a lower pressure is exerted on the floor while lying compared to when standing on the floor.
The person of mass (m) exerts the same force on the ground both standing up and lying down. This can be easily seen through Newtons Second Law ie F = ma. Knowing that pressure is defined as force over area (P = F/Area), it can be seen that the person standing up is applying more pressure to the ground.
you have decreased the area over which the force is applied, and pressure is force per unit area
Simple answer: yes In order for you to stand, talk, move... ect objects must exert a force on you. For example if you are standing on the ground, the ground has to be pushing back at you, or you would just fall through. If an object doesn't exert the same force you exert on it, then you are moving the object.
By distributing the weight over a smaller area.
assuming they all weigh the same, they would be equal. if not, the heavier one would be exerting more pressure on the ground. if you are looking for an answer relating to pressure exerted in a specific spot, calculate it by surface area.
in which situation you exert more force downward, standing or lying horizantilly?

It shows that everything that happens will a reaction of equal force in the other direction. for example when you exert 20 pounds of pressure on the ground the ground will puch 20 of pressure back.

Personally i am a dancer and i do, do pointe when standing on the amount of pressure that you excert depends on how many years you have been training i am 12 and on one toe the pressure is not that big because you have the toe padding which takes most of the pain away so the pressure really isn't that great.
Vapor materials exert their pressure in just about every direction
athmospheric pressure
external pressure is pressure that other things exert on you
