They will all contain the father's genetic information, but some will have slight differences. In Meiosis, the cell division for sex cells (mitosis is for all other cells) in a stage something happens called Crossing Over.
This is where when the two chromatids (chromosomes are made up of two chromatids) join, they exchange genetic information in the form of alleles, so chromatid 1 might have AAAA, and 2 BBBB. They cross over and now chromatid 1 now has AABB and chromatid 2 has BBAA, because they've exchanged that information.

No, they are not. This is because they are haploid (meaning they have half the number of chromosomes as other cells) and, as such, get a random spread of genes within a category (ie. dominant vs. recessive, hair color, eye color, etc.). This is why siblings formed of different egg/sperm combos (ie. not twins) aren't identical.

No they are not.
They are different because during meiosis and spermatogenesis, you have:
1. Independent assortment of chromosomes.
2. Crossing-over between homologous chromosomes.
You could also add 3. mutations, but that is relatively minor, and for most purposes, insignificant.

no they're all different. this is how they become different: http://en.wikipedia.org/wiki/Meiosis
