no you do not meet the requirements for dagpenge from a danish A-kasse.
The requirements says that you must complete an education of at least 18 months/3 semestre, and that you stayed/lived in Denmark right before the start (of the 18 months education) and again at latest 2 weeks after graduation.
This means that it is ok to complete the education in another country than Denmark, but you can not - like you have - start the education in another country and (only) finish the education in Denmark.
If you have completed a bachelor in Denmark before starting master, and you were living in Denmark before starting the bachelor, and if you have not used graduate rights in A-kasse based on the bachelor, then there is a chance that the bachelor and master can be regarded as one full education. If thats the case, then I will recommend you to ask an danish A-kasse about your right to dagpenge.
Whether you have right to Unemployment benefits as graduate in Finland, is depending on the local finish unemployment insurance legislation.
