no. the ones at the side are usually specialized for movement detection, the ones in front for pattern recognition.
the best investigated eyes are the eyes of spring spiders. The two main eyes point forward, are much larger and have a narrow but high resolving retina. To get a larger field of view the spiders use fast scanning motions of their retina. The main eyes also have color vision. I don't remember if the smaller eyes have color vision but I think not.
If you want to know more look up vision of jumping spiders. They are really cool critters.

Spiders have an efficient visual system which gives poor resolution but the ability to detect light/dark and a rough idea of size, position and motion.
There are specialized spiders with specialized eyes.
The spiders eyes are often eight (sometimes 6 or less) placed in 2 rows.
In species without specialized eyes, the spider eyes tend to produce the same TYPE of sensory input to the brain - light/dark patterns of low resolution - however their position is important for the spider to localize the prey/threat

I think not, because some are bigger than the others, right? They have the two or four big ones for vision/ forming mental images, and the rest would be for detecting movement or black and white colors...(sorry, I'm totally guessing on this-good question!)

I would say that the input is different because different eyes are pointing in different directions.
