>> as you stated there were disruption and operation suspended couple of times in last winter,so my visit to titlis/ragi/pillatus in the last week Nov only, so can you please say such suspension of service generally happened which month of the winter
The operation of the Jungfrau Railway was suspended for a short time on a couple of occasions in January, but last winter was an unusually severe one. The times I encountered cableways closed due to weather conditions were in October, December and January, but you could get high winds at any time of the year.
>> Further, i talked with all three mountain companies through mail, and all confirmed me that their mountain are still very safe in winter and sometimes windy and stormy rainy conditions may face but other day may also sunny warm days...
Yes, safety in Switzerland is first class - there is no need to be concerned on that account. You can indeed get beautiful calm sunny days in the middle of winter, even on top of the Jungfraujoch. It won't be warm though.
>> Further, as your own experiences, if cable car in the midst of the journey and disruption comes through storm and high wind, how much safe remain these journeys specifically in the last week of Nov.
They monitor weather conditions very carefully, and will usually stop operating cable cars before the weather conditions deteriorate. Although you couldn't rule it out completely, it is extremely unlikely you would get stranded mid-journey due to weather conditions.
The thing you need to consider more than anything else really is whether the top of the mountain is in the clouds, because if it is, you won't see anything.
Before buying a ticket and going up to the top, it's a good idea to check the webcams for visibility:

Make sure to have a backup plan in case the weather isn't suitable for a mountain-top visit.
One more thing I might mention if you are concerned about safety on cableways: gondolas will often stop mid-journey for a minute or so. This is normal, and nothing to be concerned about.
By the way, are you aware that the cogwheel train from Alpnachstad to Pilatus only runs until 18 November 2018, before closing for the winter? After that, you can still get up and back on the cableway from Kriens.
