This depends on where you are located, but for the most part the answer is no - unless you are a member of a law enforcement agency you will not be able to get this data from the cell phone company. Depending on the country, cell phone provider and law enforcement agency, they will probably need a warrant or court order as well.
tangentially wrt. "Depending on the country ... need a warrant or court order " - in Ukraine conflict both sides were using cell phone realtime data for tracking opponents. In particular during August incursion at least some Russian paratrooper platoons were tracked and finally hit that way. Young people who grew up having cell phones all around them and they had it with them during the incursion. Gradually both sides have learned at least to turn cell phones off - so far it seems that that is enough, at least no clear indications to the opposite - before entering combat zones.
