Missing 1st upper right molar, can my 2nd molar and wisdom tooth on the same side replace the gap?

Yes, but. Yes, but you'd need the services of an orthodontist. Another option is replacement with implant.
Yes... ... If they are moved orthodontically into position. They won't shift over in an upright manner, but rather slanted, which will cause more problems. Consider an implant. It will probably be faster and less expensive than moving those two teeth.
