Can a person pray Maghrib a little before the 'Isha prayer?

Delaying Maghrib until its last time before the disappearance of the reddish afterglow is permissible, even if it means missing the reward of praying at the beginning of its time. However, delaying it after the reddish afterglow has disappeared is not permissible except for an excuse. As for men, it is not permissible for them to miss congregational prayer except for an excuse.
