Answer 1

You need to redo some work here because it's a mess in dependencies where versions require symfony 3 and 4 at the same time (which will generate a conflict, that is not obvoius from the message you're getting right now). Same goes for deps for php 5.6 and 7.1 which are not fully compatible.
blocktrail-sdk-php already requires bitwasp/bitcoin, no need to add it in your own composer.json
https://github.com/blocktrail/blocktrail-sdk-php/blob/master/composer.json#L36
blocktrail-sdk-php also requires 99designs/http-signatures-guzzlehttp
which requires
"symfony/http-foundation": "~2.8|~3.0",
and then, you are requiring a newer http-foundation ("^4.1") in another package, specifically laravel-framework (check composer.lock)
I think your best option is to review what you actually want, review composer.json and create it again from scratch starting from the most important package.
Please start from the most important package, and match the versions to it starting from there. You'll have to review composer.json "require" node for every dependency package you need, and sometimes use some older package release (some of them are already made for symfony 4.X while some of your requirements can only handle 3.X). On github, you can easily switch to older revisions via dropdown on the top when you review composer.json to older version until the "require" matches your own dependency versions.
Please be aware you might have to prepare forks of the specific repos to make the adjustments.
If you're doing an update, remember to submit a PR with the package update, so programmers later don't have to fight the same thing :)
