The Victa Imperial reel mower is a standard item - you can find many threads on it by using the search function here.
The lngs' edger is new to me, but its layout is generally like the Alroh Imp edger, though all of the details are different. It is probably a decent edger, and was obviously factory-made, perhaps around 1965-1970. That looks rather like a Tecumseh engine on it.
The other two reel mowers are unfamiliar. The top one seems to have a very old English engine, possibly Villiers. The Webb Wasp has a generally English look too. There may be a reel mower enthusiast on the site who can help with them.
