no. there is no such case , theroretically. because, according to the law of conservation of energy the total energy in any closed system is constant. however practically some energy is dissipated in a practical case.

No, this is not possible because the the law of conservation of energy says that energy is neither lost nor gained. Therefore, if a body like a ball is thrown, the potential energy which it possessed before being thrown is converted into kinetic energy before it reaches the ground. Therefore, in this case, the potential energy is at its mimimum level as kinetic energy increases.

According to Law of Conversation of Energy, the total Energy of a system is conserved. Hence, whenever K.E is maximum, P.E is minimum.

Of course, dearie ; plenty of cases. Imagine...
1) You accelerate a car to the top of a hill, then decelerate it down the other side. At the top, its K.E. is maximum, and its gravitational P.E. is more than its ground-level value.
2) You hold two oppositely charged bodies sticking together up in the air. You pull one free and let it fall. When it hits the ground, its K.E. is maximum, and its electrical P.E.is up from its original value.
3) Throw a ball down into the ground. Its K.E. is maximum as it leaves the hand, and its gravitational P.E. is higher than when it hits the ground.
...And so on.

kinetic plus potential energy is constant, but I can imagine that kinetic energy is a maximum in some scenarios of Your system, but potential energy must be a minimum then....

I'm assuming that you mean Ek and Ep of a single mass (or system).
The answer is no since the 'total mechanical energy' of the system is, by definition, Ek+Ep and the total energy must remain constant.

no, KE and PE exist in a closed system in equilibrium
