Is/has to

Hye every one! could you please tell me the difference between these sentences?
"He is to go to the market"
"He has to go to the market"
Similarly in past.
"They had to call the police"
"They were to call the police"
and
"These rules have to change"
"These rules are to change"
"has to,have to,had to" and "is to,are to,were to, was to" ,are these interchangeable?
Thanks!
