Question

But on the spot I told them: 'Back, and quickly!

Out to sea again!' My men were mutinous,  
fools, on stores of wine. Sheep after sheep
they butchered by the surf, and shambling cattle,
feasting, – while fugitives went inland, running
to call to arms the main force of Cicones.
1; What motivates Odysseus’s men to ignore his orders to leave quickly?
2;They are seasick and want to stay on the island to recover.
3;They want to eat, drink, and enjoy themselves before setting off on their journey. 
4;They do not want to work for Odysseus anymore.

Answer 1

What motivates Odysseus's men to ignore his orders to leave quickly is 3. they want to eat, drink, and enjoy themselves before setting off on their journey.
They had been traveling the seas for such a long time, so when they finally got an opportunity to relax and unwind a bit, they did so. You can see in the excerpt above that Odysseus says that his men were "on stores of wine," meaning drunk - they wanted to feast and forget about the fact that they have to leave this island soon and venture on.
