Yes, you can.
Using the following rule which should also apply when you are Blinded (PHB p. 194):
Unseen Attackers and Targets
Combatants often try to escape their foes’ notice by Hiding, casting the Invisibility spell, or lurking in Darkness.
When you attack a target that you can’t see, you have disadvantage on the attack roll. This is true whether you’re guessing the target’s location or you’re targeting a creature you can hear but not see. If the target isn’t in the location you targeted, you automatically miss, but the GM typically just says that the attack missed, not whether you guessed the target’s location correctly.
When a creature can’t see you, you have advantage on attack rolls against it. If you are hidden—both unseen and unheard—when you make an attack, you give away your location when the attack hits or misses.
Additionally, other characters can perform a Help action to give you advantage in your turn, which would offset the disadvantage above. This could be regarded as shouting directions to you, maneuvering a creature towards you, etc.
Also, characters have what are essentially Free actions (Other Activity on Your Turn, PHB 190) on their turns, which can include speaking a few words. A DM could rule that calls of 'Foe to your left,' 'Two ten feet in front,' or 'I'm right behind you,' would help a Blinded character avoid friends and only attack enemies, albeit still with disadvantage unless given Help. Otherwise, they should have some chance of striking a friendly target, especially if everyone is clustered together in a wild melee.
