What is the meaning of the name "Helana" and must it be changed?

We have not come across a meaning for the aforementioned name. It appears to be one of the foreign, non-Arabic names that a Muslim should not use unless its meaning is known, as it might contain a bad meaning or a slogan that contradicts religion and morals. Therefore, we advise changing it if its meaning is unknown. However, if its meaning is known and there is nothing objectionable in it, then there is no need to change it.
