Fill them up with what?
If all the oceans evaporated, the amount of moisture in the air would create a runaway greenhouse effect and the temperature would reach several hundred of degrees.
As a consequence, the atmosphere would swell, and gases would start venting into space.
Pretty soon, there would not be enough water left to fill the ocean back, assuming that earth could recover from the heat and the water to condense; so to fill up the oceans again would require water from space to come crashing on earth, in the form of comets. That would take billions of years.

Firstly we would be extinct if this happened as we all need water to drink.
You might be lucky and get some volcano's to erupt which could bring back a little bit of water but not nearly enough (no where near). The earth would dry up even more because the waters absorb CO2 and take in energy from the sun directly, so the earth would spiral into a place which gets hotter.
Pushing all that aside, it would probably take at least 100 years if we had a source of water which was not on the earth of continous pumping with thousands of pumps.
There is a lot of water out there...

The atmosphere can only hold so much water, although quite a bit, enough for everyone to have their own in-ground pool. Warm air can hold more water than cold air, but I can't imagine the temperature it would take for our atmosphere to hold all of the oceans' water, cause if it evaporated, that's where it would be.

you couldn't fill them. rain comes from the oceans. 2/3 of the earth is covered with water. if they go, there will be no rain and no life.

Not sure there's a way to answer that. Probably through decades of percipitaion. If this happened though we wouldn't live long enough to find out. It would pretty much be a disaster that wipes out life.

What exactly would we be filling them back up with? Hosepipes?

You can't. There is no actual container or hole.
