Is there such a thing as a wind up generator that will supply enough power for a small air conditioner during the summer?
in case of a blackout when the temperature goes up to 95 degrees

I guess you are thinking - If you can have wind-up radios why can't you have wind-up air con?
Radios consume a few milli Watts of power. Air con would consume from 50W to 1000W. So 1000 to 100,000 times more power required for air con compared with a radio.

If you could make a main spring powerful enough to store all the energy needed for air conditioning for an adequate period of time plus all the electrical and mechanical power losses it would have to be pretty powerful. A normal healthy adult would probably have to ride a bicycle hard for two hours to power a small room ac for one hour.

It would take a lot of WIND and a big set of blades

Yes, this one, when properly wound up will power your AC unit quite well.

you could use the low power fan with ice in it its advertized as a air conditioner .. it is actually just a HUMIDIFIER it runs hot air over ice and the ice cools the air but adds water to it

Small AC units will use several hundred watts of power (a few amps at 120 V), so you are looking something approaching a KW per hour of use. It will require you to do a lot of work in the winding part, of course. No new energy, so all the energy from the unit has to come from what you put into winding it. The amount of energy needed to put in would be roughly one horsepower, which means, of course, that unless you are winding using a horse, you will have a heck of a time keeping the unit supplied with energy. Probably require a few hours of effort on your part to give it the power to run for an hour.
It doesn't sound very practical to me.

A hand crank generator? Think of efficiency. Your body will generate more heat while cranking the generator than the air conditioner can remove. Better to go swimming to cool off.
Now a couple thousand hamsters.... that's another story.

An average bicycle rider can produce up to 200 watts, so if you pedal for an hour you'll only generate enough to power a 25 watt bulb for eight hours. You're going to need 2 kilowatts for your aircon. Better get a gas-powered generator (and ear plugs) if you don't have mains electricity there.

If, by "small air conditioner", you mean "fan". Hand cranked generators (and the people cranking them) are really only good for small stuff like radios, phones, and flashlights.

anything is possible, you could see if arnazon has one since they have everything

Sure. A small a/c runs maybe 700 watts. A wind generator can supply this easily but you also need batteries. It would take about 1 horsepower to supply the a/c
