Yes they are real.
The event was organised by pastor Terry Jones in January 2013. It was uploaded to Youtube and the entire 54 minutes long thing can be viewed. The burning starts at the 51:50 mark.
In the event they burn the effigies of Obama and Bill Clinton.
The second picture of the Effigy is from an earlier time when the pastor just hanged an Obama effigy infront of his church, during the 2012 presidential elections, from a June 8th, 2012 thesmolkinggun.com article:
The Florida pastor who ignited an international furor by threatening to burn a pile of Korans has applied his subtle touch to the 2012 presidential campaign by constructing a gallows from which a likeness of President Barack Obama now hangs in effigy.
The display in the front yard of Terry Jones’s Dove World Outreach Center (DWOC) in Gainesville features a dummy wearing an Obama mask hanging from a yellow noose. Along with an American flag and a rainbow-striped gay pride flag, the scene includes an Uncle Sam dummy and a child’s doll hanging from the right hand of the Obama figure.
Nearby, the words “Obama is Killing America” are printed on a trailer. So, it appears, the creepy Jones is returning the favor.
Hang in there Obama sign
The sign was put up by Thomas Savka on his property in Wisconsin. According to both the Huffington Post and International Business Times Savka claimed that the sign was pro Obama. Both of them citing and linking to defunct reports by local affiliates of NBC and FOX.
“If it is causing this much attention, then that’s good,” Tom Savka told NBC affiliate WGBA in response to reports that his sign is distressing drivers. “If it gets you off your dead butt, gets you away from watching the football game, and go out and vote.”
The yellow sign prominently displays gallows with a tied noose next to the words, “Hang In There Obama.” But from far away, it looks like “Hang Obama” next to a picture of a noose, WGBA reports. Toward the bottom, Savka has painted in minuscule letters, “I love Obama.”
Savka told the WGBA that the message is aimed at propping up Obama during the last weeks of the campaign.
The message is “never give up. Don’t quit. I don’t care about the noose around your neck, I don’t care if you’re hanging,” Savka said.

A man who posted a sign with the words “hang” and “Obama” along with a noose on a Wisconsin highway insists the shocking poster is in support of President Barack Obama.
The yellow sign featured red letters with the words “Hang” and “Obama” with smaller blue text reading “In There” in between the larger words. To the left is a noose.
"It's my attitude for it. Everybody's picking on Obama. It's the attitude of 'hang in there, buddy!' It isn't over ‘til you're done kicking,” Thomas Savka of Redgranite, Wis., told Fox 11 Online, which has a photo of the sign on its [website].

The Obama campaign didn't buy that explanation
Others aren’t buying Savka’s explanation, including the Obama campaign.
“This type of imagery is inappropriate, and has no place in public discourse around elections,” an Obama campaign spokesman told Fox 11.

Obama as a witch doctor
A CNN article covering a Tea Party ray where this poster was shown:
Posters portraying President Obama as a witch doctor may be racist, organizers of Tea Party protests say, but they reflect anger about where he is leading the country.
The posters, showing Obama wearing a feather headdress and a bone through his nose, have been popping up in e-mails, on Web sites and at Tea Party protests for weeks.
As well as this video showing a news reporter interviewing a shop owner who put the poster on his display.
Somewhere in Kenya, a village is missing its idiot
A Daily Mail article about three anti Obama billboards put on display outside a motorbike accessories store off Route 27 in Hanson, Massachusetts, one of them saying "Somewhere in Kenya, a village is missing its idiot" with a picture of Obama.
Another one of the politically-charged posters, supporting Republican candidate Romney, shows a smiling President with communist hammer and sickle symbols added to his shirt collar.
Beneath the picture are the words: 'Somewhere in Kenya a village is missing its idiot. Obama – One Big A** Mistake America. Vote Mitt Romney For 2012!'
Obama where's your papers

Regardless of the authenticity of that specific picture, it talks about the Barak Obama birth certificate conspiracy.
