while measuring is that possible to have a reading as negitive or less than zero degree in kelvin scale

Not as far as I know. I'm currently studying Physics at Uni and studied thermodynamics last year. Negative Kelvins don't really make sense - 0 degrees Kelvin is a sort of absolute zero in terms of temperature.
Scientists still aren't able to cool anything down to 0 degrees Kelvin (approx. -273.15 degrees Centigrade) and have only come as far as about one hundredth of a degree, if I recall correctly.
If anyone gets a negative result in Kelvins, they most likely have done something very wrong. Either that or the person has miraculously solved one of science's biggest problems. :D If so, I suggest you go on to discovering the United Theory.

Temperature is a measure of the average kinetic energy of a system. At 0 Kelvin, there is theoretically no kinetic energy. However there are lots of potential energies around and interactions still occur so time still exists. If you're looking for a point when time stops then theoretically it's when you're travelling at the speed of light. Since the effects of gravity and interactions with other things in the universe supposedly happen at the speed of light, if you're travelling at the speed of light then those things can't catch you and have an effect on you. If nothing changes between you and what's around you then there is no time because there is no change to anything in which time can be said to have occurred. But yea, I digress slightly, time exists at 0 Kelvin.

It is impossible to have negative Kalvin degrees. This is due to the fact that by definition, at Absolute Zero (0deg K) there is absolutely NO particle movements. As you know, heat is directly related to particle movements. (Something that is hot, has high particle movements and something that is cold, has less particle movements) Any amount of heat needs particle movements and if there is NO particle movements at all, heat Can Not exist.

Yes, negative kelvins are possible they are physically equivalent to infinitely high temperatures. However they cannot be measured.

no is not possible... K scale zero is the absolute zero... that is the lowest temptrue there is... unless the K scale is wrong then the K scale have to be change... but so far there isn't anyone that can prove it is wrong...

no it is not Kelvin zero is the absolute zero.

according to teh law of thermodynmics..it's not possible

No that's not possible.
Laws of thermodynamics forbid it.
