Okay I've got time to kill today, it's context time !
The first picture is about Dieudonné M'bala M'bala, a french humorist who kept making antisemitic comments on his shows and invented a gesture known as the "quenelle" that is basically a semi-covered nazi salute. So yeah, I'd agree with telling him to go fuck himself with it.
The second one came out after there was a violence outburst in Egypt, involving the non-religious government and religious rebels, and was basically poking fun at the religious extremists. I'll admit that this one can very much be considered offensive even for non-extremists, but as long as that wasn't the intention…
Middle one was about the FN (far-right party in France) whose logo you can see at the bottom left of the picture. The monkey-lady is Christiane Taubira, a french minister who was criticized a lot by that same party for being, you guessed it, black. Out of context this may look like Charlie meant to be racist, but they were only showing the horrible opinions of a party that had been gaining in popularity for a while already.

Fourth picture, I don't get what is wrong with it. Just trying to get a laugh out of the fusion of two political issues that were going strong at the time : sexual slaves in the middle-east and the revision of the allocations system. They do that sometimes, I don't see how this one is more offensive than another…
Fifth one shows Frigide Barjot and Roseline Bachelot (I think), two french figures who opposed gay marriage strongly when it passed, sharing a cross as a dildo, making fun of homophobia that is. Also here's proof of them making fun of religions other than Islam.
Last one (I'm getting a bit tired of typing) shows Dominique Strauss-Kahn, a french figure known (even in the US I'm sure), for several cases of sexual harassment that cost him all credibility, and creates a parallel with the application of the Charia in Libya, which will be very disrespectful of women. I don't get the offense here either.
So here, that's a wrap, maybe I'll get called a racist, homophobe, apologist or what have you, but I don't identify as any of these and condemn them firmly. I just have something called a sense of humor, and I've actually been READING this magazine.
