On the left bike there are two men. The one with the battle jerkin is sitting on the saddle while the one in front is holding his Lee Enfield in his right hand.
Or he's just walking left beside the left bicycle.
Is that a snorkel or a periscope on the jeep in front?

Most likely a snorkel. I think this photo dates from D-Day, or just after. All the vehicles in the invasion fleet were extensively waterproofed, with a heavy grease applied around the ignition and other places on the engine, and a long snorkel tube that went from the carb, under the unlatched hood, and wired to the windshield frame. For the US vehicles, waterproofing instructions were printed on the back of a US flag sticker that can be seen on the windshield in many D-Day photos. They were instructed to remove all this stuff as soon as possible after landing.
One of the parabike riders is wearing an "invasion" vest,too.-not seen for very long after D-day (they were usually discarded)
