Greetings,
Without data, these are really difficult to accurately place to species, and in many cases, even to genus. I can give you some hints, but all of these are just my "best guesses" to get you into the ball park. The prionines are not an easy group - and without data, it's a bit of shooting in the dark.
My guesses are:
50 - Neocerambyx sp., possibly N. pubescens
51 - Hoplocerambyx sp. (likely H. spinicornis)
52 - ? Physopleurus sp. (South American in distribution)
53 - if this is South American, it could be something close to Mecosarthron sp.
54 - this is likely a Mallodon sp.
55 - likely Rhaphipodus sp., possibly R. suturalis or R. bonni (Malaysian, Indonesian, Southeast Asian in distribution)
56 - this is likely a Mallodon sp.
As I said, these are my best guesses working from images and not having locations.
Cheers!

53 looks like xixuthrus, perhaps costatus, female. Do a google search and compare.

Greetings,
Chuck - I wondered about #53 possibly being an Indo-Australian species, so I checked it against Xixuthrus, but it is lacking the elytral costae characteristic of that genus. I blew up the image to see if evidence of costae could be seen, and while the resolution drops, no clear evidence of costae is there.
It does have a superficial similarity to Olethrius, but without data, it's all guesses. I can't say for sure what it is, but I'm confident it is not Xixuthrus.
Cheers!

Hi , for 53 i think Ialyssus tuberculatus ; a classic guy in Peru and French Guiana , and for 52 Physopleurus crassidens ?

Greetings,
Beetlesdundee - Looks like you could be correct on both. The hind angles of the pronotum in #53 are hidden in the image, but upon closer inspection, they do appear to be sharply angulate as in Ialyssus. The Physopleurus is a little trickier, but it does look a lot like crassidens, especially in the form of the mandibles. I always like to be conservative working from images - especially with no locality data - but I agree with your ID's...
Cheers!
