I have not got another machine that supports maveriks/Yosemite or El Capitan just an I phone and I pad and my MacBook Pro can I still do it??
Unless you have someone else provide you with a functional installation, you are going to need access to another machine to even think about starting such a project.
You need a machine compatible with the newer OS to download / obtain the OS, and to perform the modifications that will enable your machine to boot the OS.
You need to modify a working installation. For that, you need a more recent machine to do the work.

Of course it depends on the machine. I did it myself on the same machine as OP, and it was awful. Safari was wonky, wireless was wonky. iCloud didn't function at all.
No, your machine will never be able to run Mavericks. Mountain Lion only.
I've never messed with the Apple portables after the G3 and G4 series. I wasn't impressed with the early Intel Mac portables, so I went to the Mac Pro. And I've been using it ever since.
I understand that they got better. But the first few runs of the portable Intel Macs had a lot of built quality issues. By the time they ironed them out, I had already gotten the tower.
I would expect performance to be somewhere between my Dell Optiplex 745 SFF (core2duo 2.0) and my Mac Pro as it was before I updated my hardware.
And should be quite capable. But, as you say, there may be driver issues on particular machines that need worked out.

Which one is the easiest to install with hack
The answer to that question will be different from every person you ask. The answer is to obtain the materials you need first, and try the methods discussed in detail on these forums. The easiest solution, is whichever experimental method you succeed with first.
