Can i connect 2 power sup. (5v 40a) in parallel? as an alternative, can i connect both v- to one wire and keep the v+ independent?

you probably shouldn’t connect them in parallel, but it is ok to keep the + on separate circuits with common - tied together

What are the dimensions of the 40A and 60A power supplies?

5V 40A Power Supply: 20x11x5cm5V 60A Power Supply: 21.5x11.2x5cm

Does the device work with 230V 50hz input? In 230v in Europe means 220-240V in practise.

Dear customer,The device operates under 230V 50Hz input.thanks
