Answer

The second one is better, however you can make it even more informal and natural: "I am off Thursday and Friday.'

Answer

1st sentence: it would be better to say "I'm off Thursday thru Saturday".

("I'm" is putting together "i" and "am", which is how native speakers actually talk. No one would say "I am" unless they were being very formal.)

Answer

The phrase you want is "off work". No-one uses "off job" because it's broken English.

Answer

Both are acceptable, but you can't say "off job". At least "taking off from my job" sounds better, informally.
