Yes, this is wrong when you have the same names of yours apps You also can use abstract models
class CommonInfo(models.Model):
name = models.CharField(max_length=100)
age = models.PositiveIntegerField()
class Meta:
abstract = True
class Student(CommonInfo):
home_group = models.CharField(max_length=5)

If your models are exactly the same in different applications, you're doing something wrong. Don't forget that an application is basically just a set of models, and you can use one application's models within another application just by importing them.
Can you give an example of two applications with exactly the same models?

How do I reuse a Model.
Best way to reuse model is to Inherit the parent Model class. This is how you must be doing it. Inheriting from models.Model.
from django.db import models
class trial(models.Model):
# override the parent class methods here or define your own
Also make sure that you import your apps models in the appropriate models.py file.
