Could you explain to me what are the differences between the load balancers that Amazon has? And in what cases could you use each of them?

in this link you can find the differences and explanation: link
Could you give more information about what are the requirements of your application?
Some AWS services can only be used with Application Load Balancers, for example WAF (Web Application Firewall) can only be used with ALB, so this is an advantage of upgrading your Classic Load Balancer to Application Load Balancer.
Another advantage of ALB is that you can route your requests to different "Target Groups" that are simply groups of EC2 instances. For example if your route is / app1, you can route that request to TargetGroup1 which can be a group of instances of lower-middle capacity, on the other hand, if you have a request in your route / app2, you can route to TargetGroup2 and in this you could have another type of EC2 instances, maybe an application different from the one you have in TargetGroup1. With the Classic Load Balancer, all requests actually go to any instance behind the Load Balancer compared to the example I give you with the Application Load Balancer.
I hope I am helping answer your question.
