Now that I have Photos on my computer (OS X 10.10.3), can I uninstall/delete iPhoto and Aperture?
I have no need for their functionality, since I will just use Photos (to replace iPhoto functions) and Adobe Lightroom and Photoshop for more advanced functions (including what I could do with Aperture).
To clarify, I should say, is it safe to delete the two apps (iPhoto and Aperture) without affecting my photo library?
Yes.
Equally, as the actual migration uses hard links to file in the existing libraries, the amount of storage used for the migration is minimal.
Personally I'd keep hold of the other apps/libraries for a while, but clearly your choice and if you have a definite plan going forward maybe time to declutter.
Consider an external drive backup just in case?
I read the page you linked to, as well as your post.
I don't mean to delete the iphoto library. I know that's what Photos is referencing (at least for all photos unedited by Photos before 10.10.3 update).
I mean the apps. They don't take up 'minimal storage', instead aperture and iphoto apps take up around 2.5gb of space. I have a large SSD, but I would still like this space back.
There doesn't seem to be any clear information about this or a guide from Apple. I'm surprised, since so many mac users are running there systems on tiny SSDs, where space is very valuable.
What guidance do you need? If you don't use the apps then delete them, same as word processors, database app, notebook apps etc etc
My concern is that there is a shared library, and by deleting the two other apps, the ones the new one relies on, that the there might be some data loss. I wanted clarification. If an app is intended to replace two other apps, then why doesn't it replace it?
Do you understand me now? It's not like any other app that I don't use, it's like a software developer saying 'here is this big update that merges two pieces of software into a new one and makes a non-backward compatible library structure for the data, but we are not going to tell you the best approach, or any approach, to dealing with those old pieces of software.'

Make a bootable clone or another full backup of your SSD. You may not be able to ever reinstall iPhoto or Aperture otherwise, since they have been pulled from the App Store.
If you should discover later, that the migration of your libraries has been faulty and you need to repeat it after repairing your libraries, you will be out of luck.
Remember, it is is just one day after the first release of Photos as version 1.0. There are very likely some bugs and I would not burn all bridges before the library has been thoroughly tested and you are very confident, that this release is working well on your Mac.

The links between the library are hard links. As long as one of the libraries is still referencing one of the linked image files, that file will not be deleted from the disk. Six Colors: The (hard) link between Photos and iPhoto
What to do with Aperture and iPhoto now?
