I have a question concerning SharePoint Online customization :

Full trust solutions allow developer to customize almost everything on SharePoint On-premise. Is it possible to replicate the functionality of full-trust solutions for SharePoint Server in SharePoint Online?

    FYI this question has received flags for being too broad. It's not recommended to ask two (nor more) questions within a question, but instead have a one clear question line since SharePoint.SE as other SEs is a "Question & Answer" community. You may want to edit & reformat the question to be more concise. This, not just in my opinion, has a great association to the chance of receiving a direct and sufficient answer to your initial question.

It does depend on what you are doing, but, generally, you would adopt the SharePoint add-in model. You would create a provider hosted SharePoint add-in and give it full tenant-scoped permissions. The app will then be able to make app-only calls to SharePoint with full control over everything. Your full-trust solution for SharePoint Server would have to be re-written to use CSOM (Client-Side Object Model), since SharePoint Online does not support SSOM (Server-Side Object Model). Note that not everything in SSOM is supported in CSOM.
