Answer

The noun is generally "rise": "sunrise", "rise and fall of the empire", "rise of the land", "high-rise", etc.

Your second question is a trick one. (Is this a test? If so, it is very unfair.) It turns out "raise" is used with "pay", but only in US English. I'm not sure why, but perhaps it relates to the transitive verb (pay doesn't usually go up by itself, and someone has to put it up). There is one other use that comes to my mind where "raise" is used as a noun -- you talk about a raise in the stakes in betting or figuratively, perhaps similarly to pay.
