Contingency planning 

1-is contingency plan part of ISO22301 requirements?

The word "contingency" is not used in ISO 22301, but the whole idea of ISO 22301 is to prepare a company for a disruption. 

2-who should develop contingency plan and scenarios

Usually a person is appointed to coordinate business continuity project, and this person together with the heads of departments develops the whole business continuity documentation.

4-is there any conflicts between having contingency plan is ready and ITDR project ?? I mean is it an obstacle for DR project if I do not have contingency pls

If by "contingency" you mean the plans on how to recover your IT infrastructure, then the answer is that you must have those plans. 

Finally, do u have a kit for crisis scenarios?

ISO 22301 Documentation Toolkit contains a list of most common disruption scenarios; it also contains a documentation for risk assessment with catalogs of threats and vulnerabilities.
