Dear Loay,
Students coming from Ukraine can apply for any degree program offered by Universität Hamburg:
https://www.uni-hamburg.de/en/campuscen ... gebot.html They need to meet the regular admission requirements though.
In addition, if you they still enrolled at a university in Ukraine, it is possible to apply as a free mover for a limited stay:

Furthermore Universität Hamburg offers a study orientation program for refugees:
