Let's do the math first. One 3x3x8 (obviously large square bale) is equivalent to 72 cubic feet. The length of the trailer would be 48 ft., width would probably be around 8 feet since it's that attached to a semi truck (the number is estimated though, you'll have to measure the width yourself), and bales would be probably be stacked around 9 feet high. That is 48 x 8 x 9 feet = 3456 cubic feet.
To find the number of bales that can be fit on the trailer, divide the trailer dimensions by the large square bale dimensions: 3456/72 = 48 bales. Thus, 48 large square bales (plus or minus, depending on how high you want to stack them) would fit on a 48 ft flat-bed semi-trailer.
650 bales of hay

That sounds like an old joke but you should be able to hitch up a utility trailer to a flatbed truck with just one or two people.
Depends on the weight of the bales (both the small squares and large round) and whether that bale is comprised of hay or straw. All bales of hay, straw or baleage are sold in terms of weight (in tons or pounds), not size. Not all LRB's are going to be 5x5; a lot of them range from 4x5 to 6x6. And even then it also depends on how densely packed they are, which ultimately affects their weight. However, let's assume your asking about a 5x5 1500 lb LRB and wondering how many SSBs (assuming they are around 75 lbs each) fit into that particular bale or bales with that similar weight. So, 1500 / 75 = 20 bales; thus it is estimated that 20 SSBs will fit into one 5x5 LRB assuming the weights are what they are.

It depends on the size of the tractor trailer. Find the dimensions of the trailer and divide it by 16 cubic units.
The number of bales that can fit onto a semi will depend on the width and length of the semi's trailer and the overall cubic feet of each bale. A standard semi trailer in North America can be 8 feet to 8 feet 6 inches wide by 13 feet 6 inches high and anywhere from 28 to 53 feet long. Small square hay bales are usually 5.25 to 6 cubic feet. So if multiple the height by width, by length, you'll get the cubic feet of the trailer, you then divide that number by the cubic feet of the hay bales to figure out how many will fit in each size of trailer.
50 bales
50 to 65 bales in a squeeze, weight is a huge factor though.
This depends on a few factors: Forage quality, forage biomass in terms of lbs/acre, forage content, hayfield/pasture conditions, and the size/weight of the round bale. Some areas can get get 3 bales per acre, especially if the bales are packed light and small, whereas others may only get 2 or 3 acres per bale.
